12/9I arrived school at 9 o'clock. When I saw which classroom did we use,I discovered I didn't lesson at 9 o'clock.I was very surprised.I didn't believe it would happen to me.I was very sad and went to polyu campus to want to buy books.Badly, books shop was opened at 10 o'clock.I came back and stayed at classroom until 10 o'clock.After school, Rose , Rabbit and I went to polyu campus to buy books. Also, I bought a printer in school.But I was very hardly to bring it home.
