Dear Diary,

    Today was Sunday. In the morning I was going to have a picnic with my friends. But it was rainy. So I had to stay at home. I washed my clothes and cleaned the floor. After finishing the work, I was very tired.

    At three o'clock in the afternoon, my cousin Sarah asked me to see a film. I was happy. But I didn't find my pet kitten. Sarah and I looked for him here and there. Guess! Where was he? He was in my cap! When we came to the cinema, it was about four thirty. What a bad day!

Mary
