Sorry is a simple word but it says a lot about a person. We don't say it as much as we should. When we make a mistake we are ashamed to apologize. We feel that the other person will think less of us. That is not at all true. In fact, when you don't apologize, you come across as arrogant. That ruins relationships.
When you say Sorry you are essentially telling the other person that you accept responsibility for your actions. That attitude is what people look out for when collaborating with you.
