TIP: Own up to Your Mistake and Apologize for it! Be a Person of Integrity. Be Responsible

For this to work, there are two characteristics that Apology should always have: First, be good-natured about your error. After all, you are only human. Be able to laugh at yourself. Say, "Gee, I sure did get frustrated with you that time." Second and most important, apologize only for what you actually said or did, but not for the feelings that led to it. Examples: "I am sorry for sounding so critical, but I just had the feeling that you were dismissing everything I said out of hand." "I'm sorry I called you a bitch. That was really out of line - but you sure were pissing me off." This sort of statement frames the former explosive interchange as a mutual problem that the two of you need to work on solving in a constructive manner. And after all, solving interpersonal problems is what effective metacommunication is all about.
