Interestingly enough I was just talking about this with someone yesterday and they were saying they really pay attention to hair and to me that's kind of silly because hair you can change. I mean ...

isn't it true though that guys dig long hair on a girl?

I used to think I did, but I've met some beautiful sisters with short hair, so I don't really think it matters. As long as it's not cut so that they look like a boy it can look good.
