I once had a kid walk up to me and tell me he had to show me something out in the recess yard. We get out to a certain spot, he bends down and picks up a screwdriver and throws it at me, slammed into the side of my head. To this day I have no idea why, didn't know the kid.
I chased him back into the school building, he turned a corner and the principal was standing there talking to a teacher. I remember very clearly he drew up next to the principal and had a shit eating grin on his face.
I removed that grin from his face very quickly, he thought I was afraid of the consequences of beating him in front of the principal. He learned otherwise.
To the principals credit, once I told him the story, saw the knot on my head, AND the screwdriver I got away with absolutely no punishment.
I've never been one to start things, and in fact often times I let them go too far, but I've never actually been afraid of a fight. I used to move a lot as a kid and at some point I just got used to having to fight atleast 1 person at a new school, once people realized you wouldn't take their shit, they didn't give it.
