First I must tell you about myself. I am thirteen and I am in the third form at a school in Manchester. I have a little sister Bess, who is very silly and I have a very clever dog. His name is Pal.
What a bad day Monday was for me! I woke up late and did not have time to eat my breakfast. I did not see my books and my school cap in their places. I looked in my room. I looked in the dining-room. Then I looked into the bathroom and saw my books there. Then I saw my dog Pal under the table with my cap. I put my books into my bag, took my cap and ran very quickly to school.
The first lesson on Monday is Maths. What a difficult subject to begin the week with! Mr. Green, the mathematics teacher, took our homework. He saw that my exercise-book was dirty. He gave me a bad mark for it. Then he gave us tasks to do. I sit behind Jane, who is fat and silly. But she likes Math very much and has good marks for it. I asked her to tell me the answers, but she didn’t want to.
The second lesson on Monday is French. I like French. It’s nice to talk to your friends at the lesson in another language. Then it was eleven o’clock — time for break. Nell gave me a piece of cake to eat with my milk and then gave me her homework to copy. I think Nell likes me, and she is a nice girl.
After break we had two lessons of Latin! They are bad lessons: I do not like Latin. I talked to Nell at the lesson and Mr. Williams gave me a hundred words to write in my exercise-book after school. I wrote those words at the lesson when the boys and girls read a Latin book.
