Dear Girl who One Direction thinks is beautiful:

It's okay to behave in a manner you find comfortable.
It's okay to place your sense of self-worth in something other than your appearance.
It's okay to place your sense of self-worth in something other than what a boy thinks about your appearance.
You don't need to change your behavior to match a boy's expectations.
You don't need to be flattered when a boy writes a song all about how you should change your behavior to further please him.
You don't need to please anyone but yourself.
