What it is
Reciprocity is the unwritten agreement that favors come back around. You water my plants, I sign for your package, and neither of us keeps score, but both of us remember. Every functioning community runs on thousands of these small open loops. The debts are tiny on purpose: small enough that nobody feels burdened, real enough that the relationship now has a history.
Why it matters
Trust gets built in small exchanges that both people follow through on, not in grand gestures. Each favor given and returned is a little proof that you'll both show up, and the proofs accumulate. There's also a twist worth knowing, usually called the Ben Franklin effect: people grow fonder of you when you let them help you, not just when you help them. Refusing all help and never asking for any feels polite, but it keeps everyone at arm's length. Total self-sufficiency is a quiet way of telling people you don't need them.
What to practice
- Ask for something small: a ladder, a jump start, an egg
- Say yes when a neighbor asks you, even when it's mildly inconvenient
- Return borrowed things quickly, and in slightly better shape than you got them
- Offer before you're asked when you see someone mid-struggle
- Let the ledger stay uneven; keeping exact score defeats the point
