I was a self-conscious teenager waiting in the car while my aunt was in Safeway. I felt a pimple on my face and pulled down the visor mirror to pick it. At that moment my cousin who is 6 years older than I am walked by with one of his really cute friends - peeked in the drivers window and said Hi - I jumped a mile and wanted to die.
I asked him later at home if he knew what I was doing and he grinned and said, yeah, picking a zit! Seriously I get red-faced now a zillion years later thinking about it.
