"I needed to drop a few pounds a while back and thanks to exercise and eating right, I managed to do it. A well-meaning coworker told me the other day, 'You look great! Did you lose weight?' I hate compliments like this. All I can hear is "'You didn't look good before.' Is it ever OK to say this to someone, and what's the proper response? I just said thanks and left it at that, but it irritated me."
