When I was 16 or 17 a famous band was playing a gig in my hometown. A friend saw the singer and the bassist having lunch in the terrace of a cafe and called the rest of the girls of the gang. We were obsessed about this band and observed them from the other side of the road for ten minutes or so. We wanted to talk to them but were not bold enough. By then we had managed to get noticed and they were having a laugh about us. One of my friends said she would talk to them and they would stop laughing at once.
We crossed the road and this was the conversation:
Friend, smiley and very polite: Excuse me, we think we have met you before.
Singer, in a condescending tone: Yes?
Friend, looking embarrassed: Yes, totally sure but... Cannot...
Singer, starting to get angry: Cannot wtf?
Friend, looking positively embarrassed: Remember your name, sorry.
Singer, looking proud and terribly condescending: I AM XXXXX
Friend, very relieved: Oh! Sorry then, we thought you were our friend Tommy's dad!
We then left leaving the singer and bassist looking puzzled and poker-faced.
Some 15 years later another friend met the singer backstage after a gig in the same town. She told him she had been to their gig in town many years ago and he told her he remembered that gig. Because a bunch of teens had told him he looked like someone's dad and after that he felt old and unworthy of cool celebrity status for days. Hahahaha.
