beauty pageant: sibling rivalry

Since I was a child, I always feelthat I am in a some kind of a beauty pageant and I'm up against my elder sister because people often compares us. Unfortunately, my sister is always much better than I am. She has much lighter complexion, she is smarter, she sings much better, and she even have bigger bo0bs than I have. It is really frustrating that is why as much as possible I only want to have 2 kids, aboy and a girl to avoid the comparison and contrast that I went through and I am still going through.
