My sister thinks she's "the ugly sister" ?

That is horrible, she has plainer genes then ya'll i have brown hair and brown eyes, i think i am beautiful but also plain at times... Im sure its very difficult for her because you all are so beautiful and admired, its going to be hard on her but it might make it easier if you all hang out together at school and if you do things to make her feel pretty, like her hair and makeup and cute clothes etc. At school stick up for her! It can mess up her self esteem permanently or she might get over it once she moves away and no one knows you all!
