When you need to capture that ineffable feeling of intimacy—whether it’s romantic love, family bonds, or profound friendship—similes give you the language to make readers feel what you feel. The examples below are organized by the type of closeness they convey, each shown in a real sentence so you can adapt them immediately to your own writing.
Emotional Intimacy and Connection
These similes work when you’re describing that sense of two people understanding each other on a level that feels almost supernatural.
“like two halves of the same whole” — “They finished each other’s sentences, like two halves of the same whole.” (deep unity, romantic)
Craft note: This one’s overused in romance novels, but it survives because it works—the mathematical completeness of “halves” plus “whole” creates instant visual logic.
“as close as breathing” — “Their friendship was as close as breathing, automatic and essential.” (effortless, vital)
“like pages in the same book” — “We grew up like pages in the same book, our stories bound together.” (shared history, literary)
“as intertwined as roots beneath the soil” — “After thirty years of marriage, their lives were as intertwined as roots beneath the soil.” (invisible but strong, mature love)
Craft note: The underground imagery here is powerful because it suggests strength you can’t see—perfect for describing relationships that look ordinary from the outside but are deeply connected underneath.
“like a shadow that never leaves” — “Her best friend was like a shadow that never leaves, always there through every season.” (constant, protective)
“as synchronized as a dancer and their music” — “They moved through the kitchen as synchronized as a dancer and their music, each knowing where the other would be.” (effortless coordination, romantic or familial)
“like two trees grown from the same seed” — “The twins were like two trees grown from the same seed, different branches but identical at the core.” (shared origin, family bonds)
closeness encompasses not just physical proximity but emotional intimacy and mutual understanding—which is exactly what these similes capture.
Physical Closeness and Proximity
Sometimes you need to describe literal nearness—the kind where two people occupy the same space so comfortably it becomes second nature.
“as close as skin to bone” — “The child clung to her mother as close as skin to bone during the thunderstorm.” (protective, desperate)
Craft note: This works because it’s visceral—everyone understands that skin and bone are inseparable, making it perfect for moments of fear or need.
“like a hand in a glove” — “They fit together at the party like a hand in a glove, moving through the crowd as one unit.” (perfect fit, social)
“as near as your own heartbeat” — “Even across the room, he felt her presence as near as your own heartbeat.” (constant awareness, romantic)
“like stitches in the same seam” — “The sisters sat like stitches in the same seam, shoulders touching, knees aligned.” (ordered closeness, familial)
“as attached as a child to a security blanket” — “The old dog followed his owner as attached as a child to a security blanket.” (dependent, loyal)
“like two magnets drawn together” — “At the reunion, they gravitated toward each other like two magnets drawn together, unable to stay apart.” (inevitable, magnetic attraction)
Craft note: The physics metaphor here does heavy lifting—magnets don’t choose to attract, they simply must, which captures that feeling of inevitability in certain relationships.
“as snug as a bug in a rug” — “The couple curled up on the couch as snug as a bug in a rug, watching the rain.” (cozy, playful, domestic) For more, see CLOSENESS Synonyms: 191 Similar and Opposite Words.
Honest take: This one’s cutesy and borders on cliché. Use it for lighthearted moments or children’s writing, but skip it for serious literary work.
Unbreakable Bonds and Loyalty
These similes emphasize permanence and strength—the kind of closeness that survives hardship and time.
“like steel forged in fire” — “Their friendship was like steel forged in fire, strengthened by every crisis they’d survived together.” (tested, resilient)
Craft note: The metallurgy imagery suggests transformation through difficulty, making it ideal for relationships that have been through trauma or challenge.
“as unbreakable as a vow” — “They stood together as unbreakable as a vow, facing the criticism side by side.” (solemn, committed)
“like an anchor in a storm” — “When everything fell apart, she was like an anchor in a storm, keeping him from drifting away.” (stabilizing, protective)
“as solid as stone” — “His support was as solid as stone through her illness, never wavering for a moment.” (reliable, unwavering)
“like a chain that cannot be broken” — “The community stood together like a chain that cannot be broken, each link supporting the next.” (collective strength, unity)
“as permanent as a tattoo” — “That summer changed them, leaving a mark as permanent as a tattoo on their friendship.” (lasting impact, transformative)
“like roots holding a mountain” — “Her faith in him was like roots holding a mountain, invisible but immovable.” (quiet strength, foundational)
Wikipedia’s entry on similes explains that the power of this figure of speech lies in using “like” or “as” to create explicit comparisons that illuminate abstract concepts—exactly what we’re doing when we describe loyalty as “steel forged in fire” rather than just saying “very loyal.”
Natural and Organic Connections
These similes draw from the natural world to describe closeness that feels inevitable, grown rather than manufactured.
“like vines on a trellis” — “Their lives wrapped around each other like vines on a trellis, supporting and shaping one another.” (mutual growth, gradual)
Craft note: The botanical imagery here suggests something that happens slowly over time, perfect for describing relationships that deepen gradually rather than through dramatic moments.
“as natural as the tide to the moon” — “He followed her advice as natural as the tide to the moon, an invisible pull he couldn’t resist.” (gravitational, inevitable)
“like rivers merging into one” — “After years apart, their conversation flowed like rivers merging into one, seamless and natural.” (reunion, ease)
“as connected as the stars in a constellation” — “The family was as connected as the stars in a constellation, separate points forming one recognizable shape.” (individual but unified, legacy)
“like moss on the north side of a tree” — “He always knew where she’d be, like moss on the north side of a tree, a constant in an expected place.” (predictable comfort, familiarity)
“as intertwined as mycelium beneath the forest floor” — “Their network of friends was as intertwined as mycelium beneath the forest floor, connecting everyone invisibly.” (complex, hidden connections)
This one’s more contemporary and scientific—great for modern literary fiction or essays where you want to avoid tired nature metaphors.
“like the ocean to the shore” — “She returned to him like the ocean to the shore, inevitable and constant despite the distance.” (cyclical, persistent) For more, see Simile.
Everyday Casual Closeness
Not all closeness is profound or dramatic. Sometimes you need similes for comfortable, routine intimacy—the kind that feels like home.
“as easy as Sunday morning” — “Their friendship was as easy as Sunday morning, no pressure, no performance.” (relaxed, unhurried)
Craft note: The temporal specificity here works because Sunday morning carries cultural weight—it’s universally understood as slow and unstructured.
“like your favorite pair of jeans” — “Being with her felt like your favorite pair of jeans, worn-in and perfectly shaped to you.” (comfortable, personalized)
“as familiar as your own reflection” — “After twenty years, his gestures were as familiar as your own reflection, predictable and comforting.” (deep knowledge, routine)
“like the hum of the refrigerator” — “His presence was like the hum of the refrigerator, so constant you only noticed when it was gone.” (background comfort, taken-for-granted)
“as comfortable as an old sweater” — “She showed up as comfortable as an old sweater, soft and requiring no effort.” (effortless, cozy)
“like knowing the way home in the dark” — “Their partnership was like knowing the way home in the dark, navigable without thought.” (instinctive, safe)
“as natural as your morning coffee” — “Talking to him was as natural as your morning coffee, a ritual that started the day right.” (habitual, necessary)
Honest assessment: Coffee similes are everywhere right now. This one works, but consider whether “morning light” or “first breath” might feel fresher depending on your audience.
How to Write Your Own Simile for Being Close to Someone
Creating original similes is a skill you can develop with practice. Here’s my three-step process that I teach in every workshop:
Step 1: Identify the specific quality of closeness you’re describing. Is it comfortable? Intense? Protective? Inevitable? Don’t just say “close”—name the texture of that closeness.
Step 2: Brainstorm objects, phenomena, or experiences that share that quality. If you’re describing protective closeness, think: umbrellas, shells, fortresses, arms. If it’s effortless closeness, think: breathing, gravity, muscle memory.
Step 3: Test your comparison by asking: Does this create an immediate image? Would someone understand it without explanation? If yes, you’ve got a working simile.
Worked example: Let’s say you’re writing about a friendship that survived a fight. The quality is “repaired but changed.” Brainstorm: mended pottery (visible cracks), scarred skin (healed but marked), a bridge after repairs (stronger at the broken place). Your simile: “Their friendship was like kintsugi pottery, the golden cracks making it more beautiful than before.”
Frequently Asked Questions
What’s the difference between similes for closeness and metaphors for closeness?
Similes use “like” or “as” to make explicit comparisons (“as close as siblings”), while metaphors state the comparison directly (“they were siblings in spirit”). Similes tend to feel more conversational and accessible; metaphors can feel more poetic but also more demanding of the reader.
How do I avoid clichés when writing about closeness?
The test is simple: if you’ve heard it in a Hallmark card or a pop song, it’s probably tired. “Thick as thieves,” “two peas in a pod,” and “joined at the hip” have been used so much they’ve lost their impact. Instead, look for comparisons in your specific field of knowledge—if you’re a gardener, use plant metaphors; if you’re into astronomy, use celestial imagery. Specificity kills clichés.
Can I mix physical and emotional closeness in one simile?
Absolutely, and often that’s where the most powerful similes live. “Like a hand in a glove” works because it describes physical fit while suggesting perfect compatibility. The best similes for human relationships usually operate on multiple levels simultaneously.
What if my simile feels too complicated?
Simplify it. A good simile should illuminate, not confuse. If you find yourself needing to explain the comparison, your reader will too. “As close as entangled quantum particles” might be scientifically accurate, but unless you’re writing for physicists, “as close as breathing” will land harder.
