I was the “body guard” in 4th, 5th and 6th grade. I walked home several girls and a couple of boys (3rd grade). that were being bullied or pushed around on the walk home from school. I was one of the biggest guys even in 4th grade.
One of the bullies called me out after school, thought it would be fun to have punch in the gut game, he punched first (I think he broke his wrist), I punched him (it was ten minutes before he could get up a walk home).
