    My name is Jim. My favorite day is October 18th, because it's my birthday. I am very happy on that day. I eat eggs for breakfast. Then my friends come to my home and play with me. We sing and dance. Someone plays the piano and someone plays the guitar. Lunch is very nice. After lunch, my parents take me to see a movie. My favorite movies are comedies and action movies. After supper, my parents, my sister and I watch TV. Then I go to bed at ten thirty. I don't do my homework on that day. I am very tired but happy on my birthday。
