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 ear． Perhaps you'll be'able to stay longer next time you come． A week is not really long enough， is it? If your school has five weeks holiday next year， perhaps you'll be able to stay with us for two or three weeks．
We have been back at school for three weeks now． It feels like three months ! I expect that you are both working very hard now that you are in Grade Eight． I shall have to work hard next year when I am in Grade Eight． Tom and Ann won’t be in Grade Eight until 2011．
They went for a picnic yesterday， but I didn't go with them because I cut my foot and I couldn't walk very well． They went to an island and enjoyed themselves there． Do you still re’member the island? That's where all five of us spent the last day of our holiday．Tom， Ann and I send our best wishes to Betty and you． We hope to see you soon．
Yours sincerely，
Michael
