Essay topic idea

I think I'm going to do my essay on the languages that we form within groups of friends and family. I hope to use Margaret Finders story about notes and June Jordans essay on black english to help me explain my topic. I mainly wanted to use those stories because it shows how there are different languages used in different cases. We may write standard english on an essay but when it comes to notes passed to friends we use things like OMG and WTF and JK to shorten words and we even speak them in those shorten forms too. Also within the family sometimes you learn different ways of talking to eachother because your with eachother all the time that you dont need to say everything to get the point across, if you know what i'm talking about. Those are just a few ideas i have so far, hopefully i'll come up with more. If you have any advice for me please give it! I need all the help I can get!. Thanks.
