Harmonizing should be genuine
Harmonizing can be misused. We can try to fake sincerity.  Harmonizing should not become a self-conscious, manipulative imitation of a Friend’s behavior.If this should happen, Friends are likely to detect and then resent the pretense.
                                                                                       
We should never repeat something that would make another feel uncomfortable, such as stuttering or asthmatic breathing. We do not express pain that is more profound than what Friends experience. Common sense should prevail here.
