I've got a problem of easily forgetting things. I am the monitor of our class. One day, when I arrived home after school, I suddenly remembered that my homework sheet was left in the classroom. So I ran back to my school in a hurry trying to get it. As soon as I stood in front of the door of our classroom, I realised that the key of the door, which was kept by me, the monitor, was put on my table at home. Oh no! How serious this problem is! I really need to correct it.
