I'm perfectly happy being niceti someone. The problem arises when they aren't nice to me and mine.
There are more people like this in the world than not. We are usually only shown the bad side of the coin. The trick is to do things like this without expecting anything in return.
Whether one believes in a religion or not, and whether one believes in rebirth or not, there isn't anyone who doesn't appreciate kindness and compassion. - Dalai Lama
