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.

Yours,
