As a rule, we have a test about some usual things in our life every two months. During my second month of nursing school, our teacher gave us a pop test as usual.

    I was a serious, hard-working and careful student, so I passed the questions easily until I read the last one, "What is the first name of the woman who cleans the school?"

    I thought this was sure some kind of joke. I saw the cleaning woman several times. She was tall, dark hair and in her 50s, but how would I know her name? I handed in my paper, leaving the last question blank.

    Before the class ended, one student named Nancy asked our teacher if the last question would count toward our test grade. This was also all the students' question. We all wondered why he gave this question in the test, because we all felt it meaningless.

    "Certainly," said our teacher. "In your life you will meet many people. All of them are important. They should get your attention and care, even if all you do is smile or just say an easy 'hello' ." We all kept silent after hearing this.

    I've never forgotten that special lesson. I also learned her name was Dorothy.

    In the mid 1990s, people started doing business on the Internet. At that time, there were two kinds of companies. First, there were traditional companies which sold things in shops. Then, there were Internet companies which didn't have shops; they sold things only over the net.

    Traditional companies didn't want to lose any business. Quickly, they created their own website and began selling things over the net. These are the so-called "brick and click" companies. Many shops are made of brick, and you click on your mouse to buy things with your computer. That's where the name "brick and click" comes from.

    By the late 1990s, e-businesses like Amazon.com and Buy.com were in trouble. Their profits were not very high, and there was a lot of competition. Many of these businesses lost a lot of money, and in 2000, many e-businesses went out of business.

    Why are "brick and click" companies, like Barnes & Noble, Toys "R" Us, and Walmart so successful? First, many customers know and trust their names. Their websites, like walmart.com, are easy to remember. These companies also have a lot of experience. They know how to run a successful business.

    In the world of e-commerce, companies are fighting for every dollar and every customer. Will "brick and click" companies win the war? Only time will tell.
