This afternoon, I passed the entrance to the car park for the Hampton Court Flower Show. Motorists were being greeted by official looking signs which stated: "Please stagger your journey home."
How exactly does an individual driver stagger his or her journey?
While it might be a good idea if the owners didn't all return to their vehicles simultaneously, I doubt they're in much of a position to know when the other visitors have had enough of the flowers.
I wonder what a psychology professor would make of it all? Or a philosopher?
