Social Spying Utlity

Usually I'd try to get all introspective on this... but I can't really be arsed at the moment.

I love Facebook, it's interesting to find out that you know someone that someone else knows too.
China Bee AKA Good Kisser Bee is Facebook friends with a girl I went to high school with who was now in Ireland.
Naturally I enquired with China Bee how he knew her, and he said they'd met when he was working at Wenty Leagues.
This satisfied my interests, she was a nice enough girl, a little weird and defiantly not in the cool group at school but that was all I needed to know.
As if by some sort of out of worldly coincidence I run into Irish Girl at Valleygirl. Of course the first thing that wants to escape my lips is to ask how she knows China Bee but I fight the good fight and persist with the meaningless small talk for a good four minuets before attacking. Turns out she and China Bee 'hooked up' last year.
NOW THE ONLY IMAGE I HAVE IN MY HEAD IS OF THEM SHAGGING WHILE WERE MAKING CHIT CHAT ABOUT PEOPLE WHO'VE GOTTEN KNOCKED UP SINCE SCHOOL!
At first the image was sort of her head on my body, non imaginative sort of way and then all of a sudden I have to look away from her as she speaks because its like ammunition for the porno which is rendering itself in my brain! ARGH
They say when you sleep with someone you have sex with everyone they have had sex with... well I wasn't prepared for one of them to have been someone I wasn't particularly fussed with six years ago.
And now I still have the image in my head.
Geez.
