Can someone explain to me the strange inner workings of my brain?

So, this guy I sort of used to go out with (and who I may still be just a little bit hung up on) and I are Facebook friends. I also never took him off my AIM buddy list after we stopped sort of going out. Anyway, I thought he'd get a kick out of the new Jonothan Coulton song. I'm trying to figure out why exactly I felt comfortable messaging him on Facebook with the link, but not IM'ing it to him.

Oh, I feel so old.

Did you ever peruse a list of celebrity birthdays and come across someone you absolutely loved as a kid but haven't thought about in years and suddenly realize how old you're getting?

Yeah.
