I caught my ex-girlfriend cheating on me with her ex. I knocked on the door of her house after seeing his truck in her driveway and she answered the door in his t-shirt and nothing else.
Ever notice it's always a guy with a truck?
And it's true; Girls hate being caught. As if they have some divine right to do whatever the @#$% they want.
And they say that men are dogs.

Oh, hey, I've got another one.
So a friend of mine, who migrated to Canada a couple years back, right? We were talking, and she was trying to fool her friends into thinking she had a significant other (I don't get it either), and somehow, I got hit with that stick (bad timing?).
So, after a couple exchanged photos, hearts in WLM screen-names, etc. people believe it. We were pretty close, so hey, we left each other's names in our Screen-names. Everything's peachy, her friends are aptly fooled (Canucks are kinda simple though)... Then one day, I'm out of her SN, and she switches email addresses, and cancels her FB account. And that was that.
I was kinda just going through the motions, so I wasn't really concerned, but it hit me as strange. That was about 2 months ago.
Today, while I was having dinner...
Girl: So, David, you're officially my boyfriend at school. According to my friends.
I got to about "you're officially my boyfriend-" before I nearly choked on my food.
I don't get it, am I single or what?
