“…writing is antisocial. It’s solitary as masturbation. Disturb a writer when he is in the throes of creation and he is likely to turn and bite right to the bone…and not even know that he’s doing it. As writer’s wives and husbands often learn to their horror.
And – attend me carefully, Gwen! – there is no way that writers can be tamed and rendered civilized. Or even cured. In a household with more than one person, of which one is a writer, the only solution known to science is to provide the patient with an isolation room, where he can endure the acute stages in private, and where food can be poked in at him with a stick. Because if you disturb the patient at such times, he may break into tears or become violent. Or he may not hear you at all…and if you shake him, he bites.”
