Bought a box of Krispy Kreme doughnuts for big treat Sunday breakfast yesterday and was very struck by the fact that everyone buying them was excited, drooling, absorbed and happy as they agonised over whether to include a maple glazed or a chocolate sprinkled in their box. It was spell binding to watch such universal positivity. So I've decided that if social work doesn't work out for me I'm gonna become a Krispy Kreme doughnut vendor selling happiness in a box. What would your alternative career be?
