Dear Mary,
Thanks for your last letter. I'm so glad that you have been able (at last! ) to arrange aholiday in Australia. As I fear I won't be able to meet you at the airport when you arrive, nor will be able to be home until later in the afternoon, so here are some instructions and suggestions.
Presumably you will be tired and want to sleep. But if you feel like some exercise after thatlong flight, you could stroll down to Cooper Park, which is only ten minutes away ? you can see it from the window.
Cheers and looking forward to seeing you.
Yours sincerely,
Annie

Dear Mrs. Gorden,
I'd like you to know how much the week at your lovely house meant to me. I not only enjoyed myself immensely, but also I felt relaxed and refreshed as I haven't felt for months.
Please give my love to Helen. It was so nice being with her again just like our old days together at school.
Many thanks to you and Mr. Gordon for asking me.
Sincerely yours，
Jean Brown
