This is a wonderful story- I read it before but couldn't remember where so thanks for posting this OP. This is the attitude all parents should take with their children so they have a positive self-esteem.
I remember getting my hair pressed all the time when I was younger and even though my parents always told me I was beautiful I never thought my hair was because it was always getting "fixed". It goes to show that when you constantly straighten a child's hair or decide to relax it you are sending a message that their hair is not good enough in its natural state.
