I am in agreement with the posters here. One other bit of insight on walking away. Sometimes people have an opinion of you that is not true which is not up to up to dispell, but you are constantly doing so. Whatever has given rise to the other person's opinion usually is nothing you've done wrong. An example is quietness, often taken to mean a negative (confidence, timid, afraid). I find that quietness means the person just doesn't have anything to say, has a good sense of humor and is sometimes the opposite of the rumor.
