(Proverbs 17:9 KJV) He that covereth a transgression seeketh love; but he that repeateth a matter separateth very friends.
I always seem to want the last word. I think it is built into many of us. When you get two last-worder’s together it makes for a long conversation. Each “repeats” (8138) the same idea even if they use different words. If it goes on long enough it “separates” (6504) us from our “friends” (441a).
I still have not learned to squelch this tendency. It usually takes several rounds before I wake up to what is happening. Usually at that point I try to find a way to back off. That involves being the loser in the discussion. What helps me is an awareness that I wasn’t going to win anyway. What I find amusing is that the other person doesn’t want to let me go. They will make repeated statements hoping to pull me back in.
So? Let me go when I back away. You don’t know me by sight? Then extend the courtesy to anyone who tries to withdraw from a pointless argument. You may save a friendship.
