I gotta say I'm guilty of doing the same thing when I talk to my Indian friend that owns the gas station I go to. I catch my self talking to him like he sounds to me. I guess subconsciously I think it helps him understand me.
I thought it was hilarious. Just like how people mysteriously pick up a Spanish accent when talking to a Chicano.
