Oh wow! More "seasoned" adults tend to say whatever they want. I am usually ok with it but right after I had my last son and couldnt get the weight off like I wanted because I also have a thyroid condition my mother in law picked the WRONG day to call me FAT.... SO I politely told her I had just had a baby and what was her excuse
lol... Needless to say she has never commented on my weight again. But it could be that this lady likes to put others down to make herself feel better... You can either continue to smile and endure or "sweetly" tell her you've noticed the same thing about her!
