Awkward things strangers have said to you

I'm the spitting image of my father (when he was young, I suppose...) and have his same mannerisms and voice. So obviously I frequently get complete strangers coming up to me and asking me whether I'm his son. I never know how to answer nonchalantly... I always end up being awkward and mumbling something stupid.

Once however it was really funny... I was walking in the street, and I see a car pull towards me and the driver lowering the window. I politely stop and wait for him to speak. He's going to ask me something, but I actually see him change mental gear and instead of asking me his original question he says "Are you... his son?"

-_-' I don't know how I managed not to say "You stopped to ask THAT?"

Then he said that he had actually stopped to ask for a direction, but when he noticed the similarity he just couldn't resist asking me about my old man.

So... how much does complete facial plastic surgery cost?

Jam it back in, in the dark.
