I sympathize. Once someone gets under my skin, I have trouble letting it go. I have a co-worker who drives me SO crazy, that even on his good days, he asks me what's wrong.
I'm not good at confrontations, but if I wanted to stay in the group, I'd probably say something off-handed like, "I won't critique your ride, if you don't critique mine (insert smile)." Leave her thinking. Is everyone perfect all the time?
