I'm waiting for my hair to grow longer now. They say it's asign of a steady relationship for a woman to claim territory over hair and then to chop off all her lovely locks. To analyze
--it could be that they want their boyfriends to worry about them.
--it could be because they want to gain power over said friend.
--it could be because their hair is hot.
--maybe the want to donate it to a good cause.
--maybe it's a war for what is mine and what is yours in the relationship.

Why do girls cut their hair?

--she wants to look edgy.
--she's tired of being beautiful.
--it's grown too long, so as they can tuck it into their pants.
--she needs change.
--it's because you have her body, but you can't have her hair.

Whatever it is, it's growing out now.
