Dear Tiny,
My name is Jack. I'm a dog. I'm kind. I am not big. I don't live in London. I live in the country. I have not got many friends. But I've got two true friends. They're a donkey and a cat. The donkey doesn't like winter. But he likes summer and green grass. The cat likes all seasons. Would you like to visit us in summer? It 'll be sunny. It won't be rainy. I'll be happy to see you.
Best wishes,
Jack
