I thought most people are proud of themselves for loosing weight???
If someone came up to you after dropping 50+ pounds & said "Hey! You look great have you lost weight"? Wouldn't you be happy to answer with a resounding
"yes thank you 50 pounds"?

I know the bad remarks are meanness, stupidity and/or jealousy and totally uncalled for, but people are often all these things & a bag of chips, so wouldn't a snazzy comeback be good in these situtations?

Like...
"Hey didn't you know healthy is the new cool!"

"Thin & healthy doesn't run in my family, I had to chase after it!"

"You know rudeness doesn't bounce off me anymore & that was kinda harsh!"

Believe me I am not trying to be trivial about these things but I have always found that a quick wit trumps a stupid remark every day of the week!
And my heart goes out to everyone that has had their feelings hurt...
