that day i learned a lesson英语作文

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.
