Life is more inspiring and fulfilling if you give people the benefit of the doubt. When someone does something that irritates, exasperates, hurts or confuses us, the temptation is to think their intentions are based on our knowledge. How could they possibly have done that if they are a good/ intelligent/ caring person? We have limited attention and memories. We have conflicting goals and inconsistent beliefs. Very seldom are people's intentions malicious. Like watching a movie, it helps to suspend disbelief. People make mistakes, but it is often not for the reasons we think. We can cut each other some slack.
