Every unanswered message, unsent thank-you, and overdue check-in is a tiny line item. Here's how to pay it down without burning out.

Relationship debt is the cumulative sum of every interaction you owed someone and didn't make. The friend who messaged a month ago. The colleague who recommended a book and asked what you thought. The cousin who sent a baby photo and never got more than an emoji back. None of these is a crisis on its own. Together they form a quiet weight you carry around without naming.
Relationship debt has the same dynamics as financial debt. Compound interest: the longer you wait to reply, the more awkward it feels to reply. Asymmetric visibility: you see your own queue, the other person sees only the silence. Avoidance bias: the older the unanswered message, the more you skim past it instead of opening it.
Don't try to clear the backlog in one weekend. That's the relational equivalent of paying off a credit card by skipping rent. Instead, pay by sessions: one five-minute session per evening, three messages per session.
Use the overdue list as your debt ledger
Contact Book's dashboard surfaces who's overdue against the cadence you set. That's your debt list - prioritise oldest first.
The mistake everyone makes is over-explaining the silence. Don't. "Sorry it's been a while - thinking of you." "Just saw your message from forever ago, would love to catch up." Done. The other person almost never holds it against you; they're frequently relieved you reached out at all.
