I'm not 100% sure how mafia works, and I've played six games. If you want to talk to an expert, ask Lava. But I understand about business. You should play sometime, though...maybe sometime school isn't in session. Mafia is a blast, and it's not that time-consuming, unless you're either running the game to PM'ing other players to a ridiculous degree.
Yes, I have a "cooperating teacher." I have to teach three lessons under her, two of which she grades me on; and, the rest of the time, I am supposed to act as a sort of teacher's aide. The school experience isn't easy, but I'm glad to be getting it. I was homeschooled, so the grade school atmosphere is a little foreign to me anyway; and, in a school where most of the kids come from rough backgrounds, I'm starting to understand something of what inner-city teachers face, and why a lack of student achievement isn't always the teacher's fault. I'll probably end up at a private school, which is why I'm glad to get this experience now.
