Bully story: I entered public high school in my Junior year, having hated the 2 previous private prep schools my parents made me attend, and deliberately trying to flunk out.
But I lacked the skills for the more rough-and-tumble environment of a public HS, compared to those exclusive boys prep schools, and a bully soon latched onto me. He was especially annoying in the lunch room, and one day he started poking my ice cream cup with his dirty fork.
A small offense, but I'd had enough of his constant persecution.
"You wanna play with my ice cream? Here, lemme help you..." And I shoved the ice cream cup right into his face, to cheers from the other students at our cafeteria table.
He tried to punch me, but I dared him to step outside where I'd take him on. We went outside the ground-level cafeteria, where I pounded him real good. Other students were pressing against the windows and yelling, finally getting the attention of the teachers who were the lunch room monitors.
We were both hauled off to the Principal's office. There I reverted to class, and calmly informed the Principal that if I was subjected to further bullying my parents would refer the matter to their attorneys. Mind you, this was 1965.
The bully & I were both given a stern warning and sent back to our respective classes. Thereafter he showed me a lot more respect, actually grateful that I had possibly saved us both from a suspension. And he never bothered me again.
