Atheists, do you ever get tired of people in real life continuously asking about your atheism?

I do...it seems like almost every time I hang out with my friend Kelly, she always brings it up (she's a Christian) and she even sometimes tells people I just met at a part that "he's an atheist!" in a joking way but still...I don't think my lack of belief should be such a big deal. I hate the discrimination. I live in northern Texas too which doesn't help. Anyway, do you get tired of having to talk with people about your lack of belief in a god?
