I'd like to share a little story with you about something that happened when I was four. I remember it clearly. Our loving family dog was nearing the end of his life. My father picked him up and put him in a little bed we had made for him. Our dog, my companion, whom we had cared for, bit my father when he attempted to help him. How could he? Why? I couldn't understand it. I didn't like him anymore. I hadn't thought about that story for a long time but something that happened last week brought it back to me. I went to speak with a friend. When I knocked on the door, I met in an instant an angry look and a few harsh words. When the door was slammed in my face, I stood there shocked, and in a rush, I was reminded of my dog bit my father 20 years ago or so. What brought that story back was that same feeling of betrayal. Both stories taught me something the next day. You see, when I got up in the morning and was told my dog had died, it became clear to me that he must have been in great pain. For him to have bitten a family member, he could not have been himself. Much the same for the other story when I learned that my friend's wife had just left him. We are all beings of our environments, our opinions and feelings. And all of those things can cause you to say and do things that can't be understood by those who are not in the same situation with you. If you meet someone either behaving out of character or acting in a way that doesn't seem to fit the situation, put out your hand and be patient when you think it is least possible for him to do so. You may turn around a story that has a sad ending simply by your actions. The author's friend said harsh words to the author because  _  .
