I'm quite close to my sister. Really, like best friends. It wasn't always so. She is three years younger than me and we were fairly competitive growing up. I was studious and captain of the debate team. She was head cheerleader and student body president. But as we grew up and moved away, that seemed less important. Her son is my youngest son's best friend. Sometimes I am sad that my daughter does not have a sister. Not sad enough to have another baby, don't get me wrong there, but still. I would miss not having mine.
