Years ago I was working in an office where I had taken a joke too far and that person was no longer speaking to me. He was known around the office as a person who would cut people off permanently. I read an article in Guideposts about a kid sending another kid with whom he had a disagreement with some home-baked fudge and the relationship was restored. I decided to do the same thing with my co-worker. I was warned it could go one of two ways 1) he could accept the gift and no problems or 2) he could slam the fudge down on my desk and make a scene. I took the chance and it turned out for the first time this person actually spoke to me and our differences were resolved to the amazement of the whole office. I have used this technique many times over the years to good results.
