Speak Correctly

I've gotten into the habit of saying some slang words. I say "dis" for disrespect and "true that" for that's true. Why do I do this? I learned to speak correctly, why do I say some things wrong? Out of laziness I suppose. Maybe because everyone else does. Whatever the reason, I'm going to stop.

That's probably how language gets changed. People stop saying the correct word or phrase and use slang instead. Not me. If I say a slang word I will correct myself. I might not catch the slang I say. If I use an incorrect word, would you correct me, please?!
