根据短文内容,选择最佳答案。

Dear Tim,

Today is Saturday. It's 7:00 in the evening here. I'm writing to tell you something about my life. My father is watching CCTV news. That's his favorite program. My brother is playing computer games. My dog Dick is taking the hat to me. He wants me to put it on and go out for a walk with him. What a clever dog! My little sister is practicing playing the piano. It sounds beautiful today. Outside, I can hear cars and buses coming and going quickly. Also there are some boys playing ball games.

    It's really a noisy but happy evening. Do you think so?

    What are your family doing? I know the time here is thirteen hours ahead of (提前) that in New York. Are you getting up?

    Please write to me soon. Best wishes!

Yours, 

Denial
