One takes the same route day after day but never notices the full picture. He walks, runs, takes the bus or drives and is able to provide a very detailed description of the route. But there are holes in the picture, those things which are obvious but which he has not noticed before. If only he tried the other side of the street or the reverse course, he would find extraordinary things staring at him. Once noticed, they become newly acquired friends, their presence obvious from time immemorial.
