When I was in primary school, I got into a major argument(争论) with a boy named Michael in my class. I have forgotten what the argument was about, but I have never forgotten the lesson I learned that day.
I was convinced that I was right and he was wrong, and Michael was just as convinced that I was wrong and he was right. The teacher decided to teach us a very important lesson. She brought us up to the front of the class, placed Michael on one side of her desk and me on the other. In the middle of her desk was a large, round object. I could clearly see that it was black. And she asked Michael what color the object was, “White,” he answered.
I couldn’t believe he said the object was white, when it was obviously black! Another argument started between Michael and me, this time about the color of the object.
The teacher told me to go stand where Michael was standing and told him to come and stand where I had been. We changed places, and now she asked me what the color of the object was. I had to answer, “White.” It was an object with two differently colored sides, and from his viewpoint（视角）it was white. Only from my side it was black.
My teacher taught me a very important lesson that day. You must stand in the other person’s shoes and look at the situation through their eyes in order to truly understand their perspective.

Every day of the week has its own color. Here’s what colors days show.
Monday is like a white paper for you to picture anything you want. On Monday almost everyone chooses to close their mouth to be silent and wait for something. So it’s white.
Tuesday is light gray. As you might have already guessed, Tuesday is more interesting than the first day of the week. It means that the white paper starts getting some colors on it.
Wednesday is red because you’re in the middle to start an exciting weekend. You should meet friends and have fun together on the day. So this day is with colorful activities.
Thursday is dark gray. Thursday shows a condition of mind that suffers from the difficult tasks and expects Friday.
Brown is a color full of surprises. Friday is brown because this day is full of things that are interesting and exciting.
Green should be a favorite color. The same goes about Saturday because it’s people’s favorite day of the week. You’re free today and will be free tomorrow too. Green color helps people relax.
