A generous promise should become clearer when you ask how it will work.

Real offers get more solid when you examine them. Dates appear, amounts get named, and the person is usually glad to have been asked. Offers made to produce a warm moment tend to go the other way, growing vaguer, turning into a question about whether you trust them, or quietly changing subject. Asking how something will work is not suspicion, it is the ordinary next step.

When someone promises something large, ask when, how much, and what happens if circumstances change. Watch what the question does to the offer, and take that as your answer rather than the original warmth.
