“Good old Canada geese. When I was a kid, my mother told me that when the geese leave, snow falls from their feathers . . . then they splash into the waters of the southern hemisphere and turn it blue, swallowing liters of it and coming back our way to paint everything in spring colors. It wasn’t total make-believe; every year when they take off, you know winter is on its way, and then they come back and bring the nice weather with them.”
