The Wilsons
The Wilsons never ate gammon on a Tuesday. They once had a pet piglet called Simon who was mauled by a neighbour’s Rottweiler on Shrove Tuesday. It was their way of respecting Simon’s memory. They also had a dietary embargo in place on shroves, but never had the opportunity to exercise it.
I wonder if anyone here has any irrational taboos or rules that the rest of us wouldn’t understand; even if we knew the reasons for them.
Post Script: The Wilsons are no longer with us. They both died of food poisoning from eating undercooked chicken; on shrove Tuesday, as it happens.
