I hate when people touch my hair!! But I've never yelled at anybody for it. There's not many curlies in my school, so I guess they just don't know any better.
Once, one of my friends, while we were on a youth retreat with church; pulled the side of my hair while it was still drying, ruining my curls. I was so P.O'ed, lol. I wore my hair in messy buns for the rest of the week.
Hair touching is one of my biggest pet peeves for sure. But don't get me wrong, I don't completely freak out about, it's just so annoying.
