Body issue

I have a really good friend who has a problem I wish I have. No matter what she does, no matter what she eats, she never gains weight! I think she even tried the best weight gain supplements and she did gain a little bit, but not enough to give her the "curves" she's wishing for.
She's stick thin for as long as I can remember. Even after two kids. Very lucky, indeed!! I tell her all the time she looks alright. And that she's beautiful the way she is. But like many of us, she is looking for something that she doesn't have.
