do unto others as others do unto u?

can't stop others from saying what they want but it just doesnt feel good when you feel criticized. but some people are like that, shooting off without thinking. criticizing my dress sense when they are not the least fashionable; saying that i don't need bust firming cream coz it won't sag with that little oz of fats...i dun understand why pple can be so mean with their words to someone they know. i just can't bring myself to do that. say i'm being tactful or untruthful, but i just can't say something unpleasant even though i think so.

endure? or an eye for an eye....
