I wore glasses and was a nerd. My genetics made me bigger than everyone else by high school. I changed into a meathead. No one bullied me after that. I protected other nerds against bullying.
Now I look much better than some of my friends and it's shows a shitty side of humanity when some of my bros from the gym act like they (my local friends) aren't cool enough to be with us.
Humans are very visual creatures. Most of us are very judgmental.
