On Monday we had five lessons. The first lesson was Russian. At this 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 drunk a cup of tea. I didn't drink milk. After school i didn't go home at once. I went to the library and changed my books. Then i went home.
