Hi boys and girls,
I want to have friends in your country and
to write to them. My name is Sam. I am 10.
I live in Chicago, the USA. My family is big.
I have got a mother, a father, one brother and
twin sisters. We have got a cat and a dog. My
brother and I look after them. We feed the
animals and walk the dog every day.
Christmas is my favourite holiday. We always
celebrate it together.
Please write to me about your family, your
pets and your favourite holiday.
Best wishes,
Sam
