Opposite for me.

Early growth spurt plus a lot of time working on my uncle's little pig farm had me big before the end of middle school and for some fuckdamn reason it was part of what made me a target.

I think that mainly came from my mom raising me to be a complete pacifist (possibly out of fear, that's a long story), so when the bullies realized I wasn't going to hit back they tripled down because it made them look good to harass a much bigger person.

It lasted a year and a half till I hit back and then it never happened again.
