Wow, hate to sound like a downer, but I'm having kind of a poopy day. Full of hanging out with the parents (enough to make a sane girl... well, you know, pop her eyes out with a fork) and lots of unproductive homework time. How exavtly IS average revenue a derivative of total revenue? ARGH! I'm actually looking forward to going to work tomorrow. Ahhh, simple, satisfying work. I miss work. I hate school. That didn't take me long... 
I know what you mean, I'm still trying to figure out why I want to go back.
Welcome, and where are you in Canada?
