OMG. You sound like me. If I hear a different accent for long enough, I mimic it without trying. But if I'm really excited, my accent goes straight to southern...or I talk all ghetto. It depends on what I'm talking about. I say "fancy" instead of "likes" actually. It's really weird, but idk, it's cool I think. :D Oh and, usually you don't tend to notice your accent much when you hear it constantly. Trust me, go somewhere else and you'll notice. :P
