Nudge: fight?

Strange that this nudge comes up: Friday visiting the hospital,  a brother accused me of asking about his wife and then not caring what he answered. He said I do it all the time (body language) and that everyone talks about it. Since it involved character (an uncaring attitude), I felt compelled to defend myself. After apologizing, I assured him that I did care (whatever my body language said). But he wasn’t interested in considering anything other than what he had concluded. I got nowhere and I now wish that I had simply apologized and left it at that. I have spent the entire weekend reviewing my heart, my attitudes, my motives, and dealing with the self-doubts that come from such encounters; as well as praying for wisdom and forgiveness. I suppose it will continue to bother me until something else comes along to replace it.
