Are you the middle child?

I’ve been watching a television show discussing middle child syndrome, which suggests that the center kid is definitely the most rebellious. That really fits me; I was quite the mischief-maker as a kid. Still, I often tease that my eldest brother is straight, my youngest sibling is gay, and I ended up with whatever scraps were left. Perhaps this condition influences sexual orientation too. It makes me wonder how everyone else on here relates to their brothers and sisters. Do you come first, last, or somewhere in the middle?
