I have been annoyed at someone for something he or she has done, only to find myself doing the same, or a similar thing. . . . My son left his coat in a hospital room where we had been paying a visit. It took us about a half-hour to return to the hospital, and several times I pointed out to my son how much time his carelessness had cost us. Finally, when we reached the hospital, and the nurse returned his coat, she also gave me back my watch, which, until that moment, I had not realized I had left. My son had hardly been the only one who was careless.
