hell, i don't blame the teacher for looking it up at all.
i'd be fucking pissed if someone threw something at me. Whats the point? Do you get immense satisfaction out of it? I'm all for serious punishment at schools, some shit has to stop. Some stuff is stupid though, like almost getting kicked out of class for arguing with a teacher about my opinion on something. (it was a real opinion too, about a book we read, not some stupid shit like me saying "this sucked!" i had a decent argument going)
