Many times when I am out running errands I am asked "You look familiar, how do I know you?"
99.78% of the time I have no idea who this person is. Then the person proceeds to play the twenty question game. This drives me bonkers! I usually answer that I have a very generic face and I live under a rock in the hopes that they will go away scratching their head.
Do you resemble a celebrity? I have a friend that looks like Brendan Fraser if you squint while looking at him.
