Dear John,

Thank you very much for your letter. I am glad that you enjoyed your holiday with me. We enjoyed

having you and your sister here. We hope that you will both be able to come again next year. Perhaps

you'll be able to stay longer next time. A week is not really long enough, is it? If your school has five

weeks' holiday next year, perhaps you will be able to stay with us for two or three weeks.

We have been back at school three weeks now. It feels like three months! I expect that you are both

working very hard now because you are in Grade Two now. Tom and Ann won't be in Grade Two until

2007. They went for a picnic yesterday but I didn't go with them, because I hurt my foot and I couldn't

walk very well. They went to an island and enjoyed themselves there.

Tom, Ann and I send our best wishes to you. We hope to see you soon.

yours,

Michael
