This relates to my last post. In an email exchange, someone mentioned that their friend switched to broken English when speaking to their foreign friends. When asked why, she replied that otherwise they would think she was elitist.
I find that my English language accent is SO affected by who I'm talking to that it's embarrassing and I'm self-conscious about it. I sometimes try to resist it, but it happens. I see other people doing this too, but I find mine particularly bad. It is obviously happening in my sub-conscious, but it might have something to do with the "girls playing dumb" thing.
