Dear Alfred,
My son Roger has suggested I ask you to come and spend a weekend with us here.
I am happy to do this and invite you to stay with us for this weekend. May 13-16, which happens to be our local boat club’s Spring Race Week.
If you like boats and boating, you might find it interesting, though much depends on the weather, of course.
Do let me know if you can come.
Yours sincerely
Barbara Crust
