Don't let the takers set your terms

It builds quietly. One person takes and never reciprocates, then another, and somewhere in there a rule forms: people are like this, so why bother. The mechanic stops covering shifts because the last three favors went unreturned. The nurse who always stayed late stops staying. You start keeping a ledger you never meant to keep, and the ledger slowly closes your hand.

Seneca saw the trap and named the way out: "the number of the ungrateful ought not to deter us from earning men's gratitude" (Of Benefits I.I, Stewart). Notice what he's protecting. Not the takers — you. The danger isn't that they got something free. It's that their behavior quietly rewrites yours, until you've become smaller and tighter to punish people who aren't even watching.

This is the practice that lands this week: keep the giving in your own hands, not theirs. Let the takers be a fact about the world, like weather, not a verdict on whether you stay generous. You decide how you act. They only decide how they receive it.

One ingrate is one person. A dozen is still just a dozen people, not a reason to shut the door on everyone behind them.
