Not every question deserves an answer simply because somebody asked it confidently.

Confidence in a question does not create an obligation to answer it. People ask about money, plans, health, and relationships in a tone that assumes entitlement, and the tone alone makes many people answer against their own judgment. The social pressure is real and it does not change what you owe. A question is a request, not a summons.

Have a short, warm deflection ready so you are not composing one under pressure. Something like preferring not to get into it, then a change of subject. Practicing it once means it comes out easily the next time.
