I just have zero tolerance for immaturity, and the intention behind that question is about as shallow and immature as a woman can get.
Well, I don't know... If a man never compliments his woman, then maybe it's fair for her to dig for a compliment? But I'll admit that I'm probably young and immature, so that's my own perspective. If I asked my husband that question, it wouldn't be so much "Do I look fat?" as "Compliment me because I know I deserve it!" If that's immature and shallow (it probably is), so be it!
