What it is
Every relationship is infrastructure, and infrastructure decays unless someone maintains it. Maintenance is the small, regular stuff: the reply, the check-in call, the returned favor, showing up to the recurring thing one more time. Skip it and nothing visibly breaks, which is exactly what makes the decay dangerous. Like a bridge that goes uninspected, the friendship looks completely fine right up until the day you put weight on it and discover it isn't there anymore.
It's worth saying plainly that decay is the default, not a sign of a bad friendship. Entropy doesn't care how close you were. Two good people who both stop reaching out will drift apart on schedule, no conflict required, and the drift is silent the entire way down.
Why it matters
Most friendships don't end in a fight. They lapse. Each individual missed call and unanswered text costs nothing, but deferred maintenance is debt, and it compounds the way debt does. Two years of small lapses can quietly total a friendship that took a decade to build, and by the time you notice the gap, the reintroduction feels awkward enough that most people just never attempt it. The friendship isn't dead so much as abandoned, and abandoned is a choice both people made without ever deciding to.
The math has a bright side, though, and it's the whole reason this is a practice and not a eulogy. Because decay comes from small neglect, prevention comes from small effort. A two-minute text holds a bridge that would take a hard, awkward hour to rebuild once it's fallen. Maintenance is cheap. Repair is expensive. Replacement, starting a whole new friendship from zero, costs the most of all. Spend the cheap version early and often.
What to practice
- Respond to people within a day, even if just to say you'll reply properly later
- Keep light, regular contact with the people you want to keep; don't wait for a reason
- Do the small favor when it comes up; the little debts are what hold things together
- Show up to the recurring thing even when you don't feel like it; attendance is maintenance
- Keep a short list of people you'd hate to lose, and glance at it now and then
- When you notice a lapse forming, name it plainly: "I've been quiet, let's catch up"
