" Memory is a landscape watched from the window of a moving train. We watch the dawn light break over the acacia trees, the birds pecking at the morning, as though at a fruit. Further off we see the serenity of a river, and the trees embracing its banks. We see the cattle slowly grazing, a couple running, holding hands, children dancing around a football, the ball shining in the sun (another sun). We see the calm lakes where there are ducks swimming, rivers heavy with water where elephants quench their thirst. These things happen right before our very eyes, we know them to be real, but they’re so far away we can’t touch them. Some are so far, so very far away, and the train moving so fast, that we can’t be sure any longer that they really did happen. Maybe we merely dreamed them? "
