Help, anyone?

Now for today's main post.

I've been thinking about this for a while, and I still haven't decided on what to pick. The big problem is that with all my friends, i'm pretty immature (and i mean really immature). Aren't we all? But then, around teachers and other older people, I'm as mature as i'll ever be (im pretty sure about that). They all respect that i'm a mature teenager, but then when im with my friends, and they see me, they'll think otherwise. So now they probably think im immature, but only act mature around them. The problem is, i can't decide which one to stick to. When im mature, all the staff and teachers give me alot of responsibilites, which they couldnt give other students because they think they're still immature (i sound so special, dont i? haha). I enjoy this responsibilites, but then again, i enjoy being immature with my friends, and doing what a teenager should be doing (*cough*). So if i stick to being immature, ill have fun with my friends, but lose responsibility with the older people, and if i'm mature, ill gain responsibilities, but lose all the fun with my friends. I think you're getting the point.

Help, anyone?
