Dear Don,

'Sorry - I seem to have missed it now, but at your age you'll have forgotten that you've just had a birthday.
What age are you?
Did you get a new shirt?

Young Harry unclipped your little koala from the dining room curtain today and brought it to me in the living room. Has he got the gift of divining with rods? We shall see.

Thanks for the copy of the portrait of you on your birthday and the photo of your cake. I'm sure you'll not mind me sharing the pics with the others. Some time I'll look out some of the photos you sent me of you and your friends at the Orrisdale Naturist Camp.

Many Happy Returns!
John

PS I've written this in large fonts because I know that your hearing is not what it was.

PPS Your birthday portrait was rejected by this website as it was "considered an afront to common decency"
