Is it normal to have the urge to avoid people in school?

I'll gladly admit that i'm really my own kind of person.. Perhaps abit weird in terms but i like it that way.. Enjoy being the one i am, and so should you.. Obviously!

Anyways, in school (Education - school or W/E) i tend to avoid most people in my class, not like being a complete Anti-Social freak.. But it's like this.. I simply do not start any kind of conversation with anyone in my class, unless with this one girl who is "Kinda" my friend, or just semi friend/connection.

It's funny because everyone is so nice, and alot of the folks in my class think i'm a funny guy, but still.. I have the urge, the drive not to socialize with any of them at all.

Even stranger it sometimes actually feels good, being all "Mysterious" and the "Where did he go" kind of guy is kind of like the way i like it... I have few very close friends but that's fine by me. Usually some of the lads in my class will often greet me with a "Hi".... "Or whats up (My name)". And of course i will respond, might throw in a little joke or two.. But i just never do that, i never do it.

Is it normal that i have this urge?.. I also often feel so misfit.. Just like, it's almost as if there is no place for people inside of my universe.. The way i think, i also tend to dislike the majority of youngsters due to the fact that they listen to what i like to call shit music.

I'm 18 btw.

- Also, i'm very against being a part of a "Group" of people, eventually following them around or talking alot with them. It's something i think would destroy my ways of enjoying myself in public places, what do you people think?.. Can anyone even relate?
