#1. Not having classes with your friends is a good thing. this was you're able to make new friends AND you're able to get your work done because you don't have someone close to talk to and fool around with. I've made a few new friends because of not having friends in my classes!

#2. SIMPLE. Tell them they are wasting their time. Nelly and I already have wedding plans. If they do not know the brand of toilette paper he used and his weirdest eating habit, they have no chance!

#3. Welcome to school. I assume you got to public school. It's just how kids are. Even in some private schools. I cuss sometimes, not all of the times. I think kids in school "do it just to be cool" or they can't think of anything else to say. Don't go near them if you don't care to hear it and if you HAVE to go near them, ignore them.
