I wonder if people who are genuinely kind and thoughtful ever reach a breaking point? Is it possible to remain kind/nice no matter what you experience? Any of you know such a person?

 The clergy?

Define breaking point.  I know I reached a place in my life where I stopped feeling sorry for everyone, even those that were unkind to me.  Learning to walk away from certain people is healthy.  I still consider myself "kind", but I won't be a doormat.

 I don't allow anyone to mistreat me PeaPod.  You teach people how to treat you and at the very least you are owed civility.  I don't understand those people who accept abuse as a way of life nor those who keep making excuses for the bad behavior of others. Different  strokes. Thank you for your reply! :)  Define breaking point? Where you stop being kind to someone who never is. You stop giving chances or time or thought or care or excuses . You move on.

 Yes. I guess that's their job isn't it bh?  Thank you for your reply! :)

i would think they would
