What Language Is My Own?

When I am at school , I sometimes speak differently, from when I am at home with my family or with my friends. At school I find myself speaking proper English, but I often catch myself slipping and using un proper English. I was born and raised in Detroit, MI so I've always had a different vocabulary than those in Illinois. I would always say things that even my friends different understand. I soon learned that sometimes I have to adopt to the language around me than using my own.  When I am around my latino friends sometimes I feel the need to only speak spanish, but in school I find myself not wanting to speak my "Detroit Street Language" or "Black English".  The way one talks has alot to do with how others view you.
