Context

“"I have no teeth, of course; my poor old back aches; there is one thing and another, . . . asthma and that sort of thing. . . . I ache. . . . The flesh is weak, but then think of my age! I am in the eighties! One can't go on for ever; one mustn't outstay one's welcome." Father Christopher suddenly thought of something, spluttered into his glass and choked with laughter. Moisey Moisevitch laughed, too, from politeness, and he, too, cleared his throat. "So funny!" said Father Christopher, and he waved his hand.” source
