It's a small world

This week I had a little online chat with a friend.
She asked me whether I could remember a guy who I apparently have talked with at a concert in my home town once. I couldn't. I can't even remember the last concert I've been at there.
She said she had a One Night Stand with this great guy last night. It turned out that he is not only the ex of her cousins long-term girlfriend, but also knows this guy she had the hots for for years since they were two.
What a small world! They randomnly met in another city.

Anyway, he apparently told her he had talked with me shortly on some concert and I had something alien-like on my head. Then it dawned on me: I was in a theatre group called Ten Sing. Once a year we wrote a play, and had a choir and a band performance included. The one with the alien was the last concert I took part, and I played an alien that was studying humans. That's about 10 years ago!
Still can't remember the guy though.

As much as I feel flattered that I am remembered after such a long time, it worries me slightly that I'm remembered with little silver antennae on my head...
