Welcome Mia,
I smiled when I read what you wrote about teasing being more about personality and vulnerability than size. I think this is so true. The son of my good friend is the tallest in his grade (probably even the next grade, too) and seems to get teased all the time. I think it's because clearly teasing gets to him, and then it's a domino effect.
My son, who is a year or two behind his classmates in age, hasn't had the adolescent growth spurt yet (he's shorter and thinner than the others), but exudes confidence. I've seen him get teased, his face expressionless, and then he moves on down the hall--almost as though he has just tolerated an "inferior human interaction". The teaser soon finds it's no fun to tease him.
