Turns out that they've been planning this since last Homecoming.
Turns out that all of them forgot to tell me until today - oh, wait, sorry, they "thought [I] was there, we're always discussing it!"
I felt like I ought to be annoyed, or hurt, or something, but in reality all I thought was "Greeeeeat. Hey, I wonder if I can find any good Cassidy fanfiction on the 'Net." (Note: I was told this as Nets and I were leaving World Religions - her to lunch, me to the library, so it wasn't quite as geeky as it sounded.)
