One time I went for a bike ride in the small city I live in.
A young woman was with children I assume her relatives. She called "Excuse me, kid." I halted my ride and faced her. "Can you take a picture of us?". I complied, and then assertively added "I'm a little older than a 'kid'". She asked what's my age, I answered "22". I think she apologized afterwards.

How old are you?
