I have two sisters, a brother wouldn't have been that bad.

That's a hard question; I do think that having a little sister or twin sister would be nicer, but when it comes to older siblings, I'm glad that I have an older brother instead of an older sister. From my experience, the big brother/little sister combo works better than the opposite, because for the most part, the older brother has a sense of protectiveness over his little sister. (I also have a pair of friends who are in the same position, although it probably helps that both my brother and my guy friend are extremely sweet, empathetic people.)

Anyway, I think the point is that I'm glad to have a brother because I think that it works better when your siblings are the opposite sex instead of the same sex. I've gotten the impression that brothers who grow up together spend a lot of time having to roughhouse, meaning that the younger one is kind of forced into a rough personality, and girls, no matter what the age difference is, will at some point end up getting in fights about sharing clothes, etc. (Even though I feel like having a twin sister would be like having a best friend sometimes, I could still see this being a problem eventually, especially if we have the same friends.)

When it comes to a little sibling, I would definitely prefer having a little sister, because I always get along really well with younger girls, but younger boys are usually too naturally rough for my liking. But the point is, I'm glad that I have a brother. :)

I do have a brother and I like having a brother instead of a sister.
