Well, I had long white hair as a child and loved it.... My mother always wanted me to have short hair and after some years I cut it.
I look rather bad with middle-length hair, so outgrowing ends in my mother telling me every day how lovely I've been with short hair. (HER mother wanted her to have long hair and she hated it...)
Now I'm so used to short hair that it stays that way. I would love long curls (mine is straight.......) but I can't imagine them anymore. So my "dream"-hair is short, even if I don't really like it. I stopped caring after my last haircut that I hate but everyone else loves. I hate getting compliments about how I look, especially if I don't think they're right......
