I think they are trying to find who they want to be and seeing if other people like their fake person they make. It is dumb to try to be something you are NOT. You can only take what you have and form it into the best you can. Your body is clay that you can sculpt into whatever you want. It might take a lot of time and money, but anything is possible if you want something badly enough.
I think they're freaks.
Hahaha, I know :)
