I cried during the last episode of Buffy, cried when Fred died in Angel, and then all out SOBBED during the last episode of Angel.
I felt stupid afterward, but these were all characters I had spent 9 years with and I guess the attachment was a bit much!
My kids' names were picked before I even knew what I was having. Xander for a boy and Anya for a girl... so I had a boy first, Xander. The next time I was pregnant it was still Anya for a girl, but I needed a potential boy name and chose Connor. I had a girl. So I now have my very own Xander and Anya (and yes I always have someone point out they were boyfriend/girlfriend in the series, but to me they were just my favorite characters).
