When you lose your grasp on your possession, you lose your reality.
And when you lose your reality, you become crazy.
Some people is not acting like you wanted to and you can't control it. Listen to me carefully they were there not going to hurt your feeling. They were there just because they are. God created them just for a sign that you are not going to act that way. They were an example of good or bad or ugly. An example of what you could have been if you lose yourself and not turn yourself into positive thoughts.
