The promise that mattered to you deserves to be repeated clearly, not hinted at more loudly.

When someone forgets something they promised, the first instinct is often indirect: a pointed sigh, a joke with an edge, a remark left hanging in the air. Hinting feels safer because it protects you from having asked outright and been refused. It also leaves the other person guessing, and guessing usually fails. A plain restatement gives them something they can actually answer.

Think of a promise you have been circling. Say it once, plainly, naming the thing and the time you need it by. Then let their answer be an answer.
