English is my Sole Language

English is considered my sole language because it is the only language that I speak, read, write, and understand. When I am talking to my friends and my peers I use slang its some what of an habit I can't help myself. When I am speaking to adults or I am on a job interview I use the proper and the correct grammar. I use the correct English when I am handling very important business or when I am talking to important people I am a very confident person when it comes to speaking English and using the correct grammar for the English language. I have a habit using English slang when I am talking to my friends or people my age and it's not like I do it on purpose it's just that it's a habit that I have and sometimes I try and break the habit but it's so hard, I want to learn to be bilingual and use other languages but it's hard because I am so used to using English, speaking, writing, and reading English.
