Boys generally mature a little later than girls. This means that when girls are standing around wondering if the boys are interested in being friends, all the boys are running around belching and making fart jokes, and running away from the girls.

So it's just natural that girls think boys are weird.

A few years later, of course, things change!

A:

The above answer is an urban legend, as I learned from personal experience. Not only is maturity in the eye of the beholder, I (a boy) have the misfortune of being the most mature one in my class.

A:

Actually, a certain chemical in the brain, makes boys mature a bit slower then girls. However, boys can be mature, or maturer then girls, as they age. Maturity can also be genetic, forced into a person, or even a quality one learns to achieve. It depends on what the boy likes, dislikes, and is like. But besides that, boys are usually a bit immature, compared to girls.

A:

It's not a chemical, it's just the way that the brain of a male of any species naturally functions, though it's much less notable in other animals. And it's not just boys who's brains are like this. In fact, 1/3 boys don't have that and 1/4 girls do.

A : you people are all right some what but i think that boys also a bit weird because they may start to like girls and not know how to show it or dont know how to tell them , but then again im not real sure , because im a female.
