I was routinely subject to 100 on 1's on my school playground. The teachers didn't see anything wrong with letting the whole class chase me down and kick me until they got bored.
My gym teacher forced me to dislocate my knees on a routine basis for a couple years, too. I was so neglected at home it never occurred to me to tell my gene donors about my knees. Finally a neighbor saw and told mom, who got me a doctor's note for gym.
