    Yesterday morning when I opened my eyes, it was half past six already. I got up quickly and ran to the

bus stop without having breakfast. As soon as I got on the bus, it started raining. "I am sure I can get to

the school on time," I thought. Suddenly, the bus stopped. There was something wrong with the bus. The

driver asked us to wait for another one.

    "I can't wait. The school is not far. I can run to school," I thought. Then I began to run, but it began to

rain hard.

    I reached the classroom, but I was all wet. The Math teacher, Mr. Li, was in the classroom. We were

afraid of him and I didn't like his Math lessons. I said, "I'm sorry, Mr. Li. I'm late."

    "It's you again, Wang Bin. I told you not to be late, but you…" He suddenly stopped and looked at my

wet clothes. Then he took off his jacket and gave it to me. "Now, take off your wet coat and put this one

on," he said kindly.

    I went to my seat, wearing Mr. Li's jacket. It was too big but I felt very warm in it. I found, for the first

time, that Math was very interesting, so I learned a lot that day.
