Did you do it because it pleased you to do so?

I think you are confusing unselfishness with altruism. People do a lot of unselfish things because it pleases them to be unselfish. These are not acts of altruism....just being sociable. There is nothing wrong with doing things to please others, I try to do so whenever possible, but it is not altruism as I am getting something out of it by being a good citizen and productive member of society. When those around me are happy, it makes me happy. Not altruistic at all!
