Have you ever had someone close to you betray you.
That friend who you were there for when their parents kicked them out, that person who you've known forever. That person that you saved from the schoolyard bully but happened to be a bully themselves. That person who you tried to make feel like a valuable human being, even when their behavior was deplorable.
Have you felt the sting of constant condescending remarks and just told yourself to let it roll off your back, and make excuses for them saying, "They've had a rough life, that's the best they can do."
Have you listened to and soothed someones ego through their divorce, bad relationships and bad choices. Have you ever thought that, that someone, really could respect you and your own choices for your life.
Have you ever felt you were losing a part of yourself when you tried to have empathy for someone who could not feel empathy for them self, much less others.
Have you reached that moment when you realize what a lot of time you wasted thinking that someone was who they weren't. Sometimes things and people are as they seem. You can read the book by the cover, after all.
Do you know that nanosecond when the spite from this person has now been aimed at your child? It's easy to see at that moment what a coward looks like. So you take the knife out of your back and realize what little effort will be needed to carry on without them.
