I actually start laughing. When I was 30 and buying a lotto ticket, the lady asked if I was of legal age (19). I told her she had made my day with that question, then showed her my ID.
Ah so nice to meet someone my age! And I can relate. My mother and I meet up once a week and have coffee, and people think we're sisters. She looks way younger than her age and we are 25 years apart.
