I will give this a try, do I just bring it up and wait for the next time she tells me I have an attitude?
You could do it either way, whatever you feel more comfortable with. Whether you like it or not, your wife resists growing up. Just because she doesn't like suggestions that she conduct herself like an adult is no reason to stop letting her know that it is what you expect from her. People will try to get away with whatever they think they can get away with. Thank you is more important than your welcome anyway. An English friend once told me they don't say your welcome. Someone says thank you and no reply is needed. Perhaps someone from England will comment on that.
