Not petty. I totally get it. I work with 2 teeny tiny perfect little snots that like to rub in the fact that they just cant gain weight no matter what they do and 'oh no, my size 4's are too big now'. I too snapped one day and got up in one of thier faces and said "continue to tell the fat girl how skinny you are, keep it up". She was like "oh i didnt mean it like that". Really? How DID you mean it then? Ive always had snide remarks made towards me because I wasnt skinny perfect like other people. I wonder if they think karma wont catch up to them one day.
