Being kind isn't a weakness

They say that you should be nice to people, but people make it hard for you to be nice to them. You can only extend your courtesy for just about so long. Is it fair that you open your heart to some one and all they do is take advantage of you. And when do you say enough is enough. You find that family be the main ones to take advantage they want you to remember that blood is thicker than water. But do they remember that blood has no feelings and humans do. We should take into other's feelings family or not, but especially family because Yes blood is thicker than water.
