Unfortunately adults can be just a mean as kids. I work in a professional setting and I had my hair blown dry straight by my hairdresser after work. Of course, everyone paid me compliments. The next day, after washing I was curly again. A gentleman that works in another part of the building said, "Why did you mess with your hair when you had it looking so nice?"
I can still hear him sometimes when I look in the mirror. I think that bothered me worse then the things that were said when I was a child.
