I know so many people that don't say anything about your weight until you lose it. Then they think they are free to comment all they want.
Like "wow, you look so great since you've lost all that weight", or "you were so fat, you must feel better now' or something like that.
My question is, if you won't say something like that to someone in their current state, why do you think it's ok to comment on it after it's gone?
Does anyone else feel that's not right, or get upset when it happens?
