Often, when I have been feeling lonely, when a book as been thrust aside in boredom [...] I have lain back and stared at the shadows on the ceiling, wondering what life is all about [...] and then, suddenly, there is the echo of the swinging door, and across the carpet, walking with the utmost delicacy and precision, stalks Four or Five or Oscar. He sits down on the floor beside me, regarding my long legs, my old jumper, and my floppy arms, with a purely practical interest. Which part of this large male body will form the most appropriate lap? Usually he settles for the chest. Whereupon he springs up and there is a feeling of cold fur [...] and the tip of an icy nose, thrust against my wrist and a positive tattoo of purrs. And I no longer wonder what life is all about.
