They lived in a flat on the fifth floor, facing a park on one side, and, on the other, through the branches of an elm tree, another block of flats as lofty as their own. It was very pleasant living up so high, where they were not disturbed by noises, scents, or the sight of other people--except such people as themselves. For, quite unconsciously, they had long found out that it was best not to be obliged to see, or hear, or smell anything that made them feel uncomfortable. In this respect they were not remarkable; nor was their adoption of such an attitude to life unnatural. So will little Arctic animals grow fur that is very thick and white, or pigeons have heads so small and breast feathers so absurdly thick that sportsmen in despair have been known to shoot them in the tail. They were indeed, in some respects not unlike pigeons, a well-covered and personable couple. In one respect they differed from these birds--not having wings, they never soared. But they were kindly folk, good to each other, very healthy, doing their duty in the station to which they had been called, and their three children, a boy and two little daughters, were everything that could be wished for. And had the world been made up entirely of themselves, their like, and progeny, it would--one felt--have been Utopia. At eight o’clock each morning, lying in their beds with a little pot of tea between them, they read their letters, selecting first--by that mysterious instinct which makes men keep what is best until the end--those which looked as if they indicated the existence of another side of life. Having glanced at these, they would remark that Such-and-such seemed a deserving sort of charity; that So-and-so, they were afraid, was hopeless; and it was only yesterday that this subscription had been paid. These evidences of an outer world were not too numerous; for, living in a flat, they had not the worry of rates, with their perpetual reminder of social duties, even to the education of other people’s children; the hall porter, too, would not let beggars use the lift; and they had set their faces against belonging to societies, of which they felt that there were far too many. They would pass on from letters such as these to read how their boy at school was “well and happy”; how Lady Bugloss would be so glad if they would dine on such a day; and of the truly awful weather Netta had experienced in the south of France.
