Where I teach, it is very American friendly. Where I live, not as much. You don't have to believe me. That is your business.
It is more in a way that I don't want to draw attention to myself. I get tired of being an oddity. I am sure that much of it is in my head, but again that is up to me! It's not that I will fake a whole conversation, but a word here and there to avoid stares is okay in my book.
