So I was thinking...
In Roald Dahl's Charlie and the Chocolate Factory the invalid grandparents all share a single bed in Charlie Bucket's house.
Four invalid bed-ridden old people in one bed.
And then there's only Charlie's mother to cook and clean.
How the hell does she get 4 people out of the bed to change the sheets???
I mean she has to do it somehow.
Those sheets would be foul.
Foul. Foul. Foul.
Just a thought.
