erm....I had a one-nighter with a girl last week and she just facebooked me. I didn't recognise her from the picture and TBH the name on the message was different to the one I was calling her last week.
Now I've just sent a reply to her saying "erm...do we know each other?" It's only on closer inspection of her photo albums that I recognise her.
I'm a bit of a cock.
