I don't get what the lady in the checkout line was getting at (was she in her flip flops and sweats?), but the other 2 don't deserve any acknowledgement at all... If someone says that to me (especially cowards from passing cars... if they were REAL men they'd stop the car and say it), I just ignore them... make them think I didn't hear it. No use giving them ANY satisfaction to let them know they've "gotten my goat"
