A few weeks ago my sister-in-law straightened her hair and was saying that her hair was better than mine because it was straight. I didn't say a thing.
Three days later I was on the phone (while she was around) and the person on the line kept saying over and over how healthy and great my hair looked. She didn't say a thing!
Because she doesn't feel good about herself she tried to make me feel the same way.
But you can learn how to rock your hair. You can set an example to your family on how to embrace your natural beauty and how accept yourself no matter what... because it doesn't sound like they feel good about themselves.
