Well you clearly are doing something. Let me see, the teacher will get mad if we aren't doing what we're supposed to.
Hey, what are you working on?
Oh, nothing really.
Well we're supposed to be doing CLASS WORK right now. If it's so important, why don't you do it at home?
What did I tell you! It's nothing, it's private!
WELL HOW ABOUT I JUST WALTZ RIGHT OVER HERE AND.... ... .... .... .... what... WHAT ARE YOU DOING!?
Gentlemen, this is a library, please lower your voice, and..... what are you doing with the computers? That's it, I'm calling up the principal.
At this school, I try to keep everything in order, so pupils can receive the education required to succeed in life. So I am saddened to see this type of behaviour. For you, this violation of the school AUP is serious. I will be generous, and give you a warning this time. If you continue these actions, I might have to restrict your access to school technology.
And for you: I am pleased by your actions to keep this type of behaviour controlled, but your attitude in that situation could have been better. I'll let you off with a lunch detention. You are dismissed.
