We are sitting, for example, at the tasteless station of some lonely minor railway. It is four hours until the next train arrives. The district is unattractive. We do have a book in our rucksack—shall we read? No. Or think through a problem, some question? We are unable to. We read timetables or study the table giving the various distances from this station to other places we are not otherwise acquainted with at all. We look at the clock—only a quarter of an hour has gone by. Then we go out onto the main road. We walk up and down, just to have something to do. But it’s no use. Then we count the trees along the road, look at our watch again—exactly five minutes since we last looked at it. Fed up with walking back and forth, we sit down on a stone, draw all kinds of figures in the sand, and in doing so catch ourselves looking at our watch yet again—half an hour—and so on.
