Alternate title: No, I Don't Want To Be Your Friend
Back when I had a MySpace account, one of my sister's ex-boyfriends tried to contact me. At the time, I thought it was a little weird, but didn't think too much of it. He had apparently tried to contact her as well, but she wanted none of it; the relationship ended very badly years ago. Also, she is quite happily married now.
I was a little surprised to see that the guy found me on Facebook and tried to contact me. No, dude, I don't want to be your friend. I never knew you very well to begin with. You dated my sister when I was twelve. We don't have old times to rehash. I'm not going to pass on any messages from you to the Sis, who wants nothing to do with you. What could we possibly talk about?
