The seats in our school reading-room are not enough for all the students. Many people get there very early to "seize" a seat every day. So do I. One day a "special" thing happened to me. And I learned a lesson that I shall never forget.
It happened on a Wednesday morning last January, just before our final examation. I got to the reading-room very early to occupy a seat. I put a book on the desk and then went to have breakfast. But when I hurried back into the reading-room, I found someone was sitting on the seat which I had occupied in advance. I ran to him immediatly and shouted at him angrily, "Go away. It's my seat." Everyone raised their eyes and stared at me unfriendly. My face turned red and I felt ashamed of myself. I took my book and fled helter-skelter before so many eyes.
I dared not go to the reading-room for several days. I learned a lesson in the reading-room. Since then I have been keeping the lesson in mind: To be polite to everyone.来自：求助得到的回答
