From my point of view.....If you are a kind person, you have a target or a sign on your back that says "mistreat me". I used to give anyone the shirt of my back if they were in need. Then I realized, I'm out of shirts. I used to believe kindness is given and received. After years of giving and never receiving, I figured it's time to, in a sense, be selfish in the good way and take care of me.
