it may come as a bit of a suprise, but I had a chair of my very own in the principles office..... while I was there for reasons other than being a bully, I saw a bunch of the school bullies come through.
once, after the "big talk" with one of them, the principle was standing there shaking his head. I told him " you know the difference between me and him?"
he said no, so I told him
" when you threaten us with your punishment, I am too stupid to know you are bluffing, and too affraid to see if my dad is bluffing or not. While that kid, knows you are bluffing, and beats up his dad"
got me out of a weeks worth of detention, he even thanked me for my perspective.
reason I was there in the first place......... trying to make powered skates out of belt sanders in shop class!!!!!!!
damned near worked too !!!!
