How unusual that so many Basenoters share the same birthday; Happy Birthday to you all.
The preponderance of birthdays at this time of year has something to do with Christmas holidays, dark nights and not much else to do 50 odd years ago I believe!
I just realised this could be read as implying that mumsy is also 50 odd, which seems most unlikely . . . on the contrary I believe the tradition of the Conjugal Christmas has continued into modern times!
