When we encounter someone who mistreats us, instead of acting in anger, withdraw.

 Later, when you are calm and more detached, reflect on that person who mistreated you. Try to imagine the background of that person. Try to imagine what that person was taught as a child. Try to imagine the day or week that person was going through, and what kind of bad things had happened to that person. Try to imagine the mood and state of mind that person was in — the suffering that person must have been going through to mistreat you that way. And understand that their action was not about you, but about what they were going through. Now think some more about the suffering of that poor person, and see if you can imagine trying to stop the suffering of that person. And then reflect that if you mistreated someone, and they acted with kindness and compassion toward you, whether that would make you less likely to mistreat that person the next time, and more likely to be kind to that person. Once you have mastered this practice of reflection, try acting with compassion and understanding the next time a person treats you. Do it in little doses, until you are good at it. Practice makes perfect.
