How do you deal with people or parents that compares their little one to yours?

oh my thats what always happen to my kids.. I always remind them never ever care what ppl say about you because you are you and no matter what ur parents always love you.Sometimes it not only hurt them but it hurts us too.So i told them all kids is diffrent they have their own special ways only we as parent must remeber that nobody is perfect.From then i guess they know what i meant.
