Answer:
Dear Paul,
My name is Simon and I'm from London. I'm 15 years old. I [go] to school in the city. I [enjoy] art and and music, but I [don't] like history or geography. Sport is my favorite subject. My friends and I play football and tennis but we [don't] play basketball.
I've got one sister. My sister Rachel is 18. She [doesn't] live at home. She [studies] computers in Edinburgh. I've got a big black dog, Ozzie. Ozzie [doesn't] know he's a dog. He [thinks] he is human! He [sleeps] in my bed and [sits] with us at the table. He's an ugly old dog but we [love] him anyways. Have you got a pet? Write and tell about your family. I want to know more about you.
Simon
