Teens more fun depending on school?

I feel like I am grouped in the other school's category... but I used to be in your shoes. It's really easy to have fun without smoking, drugs, etc. It kinda has to do with acting younger than you are... laughing at things that are remotely funny and just having a fun time... letting loose! :) I'm not sure how that sounds normal........but it is for me. My family is pretty much broke and I go to a school with a bunch of rich kids so I still feel left out sometimes, but I just make the best of what I've got.
