Researchers say that people who grew up with at least one sister are happier, more ambitious, more emotionally balanced, and more successful than people who only had brothers. So, you're welcome, Dave and Mark. Why did you have to screw me like that, though? Why does everyone else benefit from my existence, but not me? What's that? Am I being a whiny middle child? No, but thanks for asking. Besides, I did get Rachel while I was still a teenager and I think she's helped me be less insane than I was then. I like to think we help each other out with that, but maybe not. Maybe I'm marginally saner because I matured or something. Or not. Besides, once Mark got to be 8 or 9 or so, I decided I couldn't handle having a little sister like I wanted up to that point. Mark was trouble enough... And then later, Dave.
