Dear Joe,

I’m back at school now. Thank you very much for the wonderfully week I spent with you and your family. During the week you teach me how to swim, boat or fish. I really appreciate your taking me around your place and I really enjoyed me. Your mother is such good cook that I think I must have put on nearly 3 kilogram in just one week. I’ll remember forever the seven happy days when we spent together. I did hope you’ll be able to visit our school sometimes next summer. Thank you again. Let’s keep in touch with. Remember me to your family.

Shirley
