On Monday we had five lessons. The first lesson was Russian. At that lesson we wrote a dictation and did some exercises. Nick went to the blackboard. He answered well and got a "five". Pete didn't get a "five" because he didn't know his lesson. After the second lesson I went to the canteen. I ate a sandwich and drank a cup of tea. I didn't drink milk. After school I didn't go home at once. I went to the library and took a book. Then I went home.
