I would be, too. Seriously, they moved heaven and earth to get David onto the last two episoded of Buffy, but she can't be bothered to make a small cameo in the last ever episode of Angel? Someday, probably after Scooby bombs, she'll realise that Buffy MADE her carrer. Sure, she had a few rolls in hit movies (where she was killed off), but Buffy put her on the map.
Likewse, read the Michelle Trachtenberg article on Buffy.nu. While she already established herself before comming onto Buffy, the way she talks about the fans are a bit harsh.
Oh, and I hope you don't mind Vivisectvi that I borowed your banner. It was to good to past up.
