Yesterday I jokily mentioned letting my beloved cat Delmar post something here, but after giving it some thought, I'm convinced Del is cut out to be a writer. Personality-wise, at least.
Consider: He wakes up whenever he wants, can't function until he has something to drink, and when food is presented to him, he rejects it in favor of another drink. (For Del, the drink of choice is water, not gin, but still...)
A pathetic, needy display of affection is interrupted by a violent rage, followed by an extended period of sullen silence. Then, a nap, the better to avoid doing any actual work.
He's neutured, which makes him perfect for sad, unconsummated affairs with an ever-younger series of "research assistants" and being a cat, he's not capable of doing anything more than wandering up and down a keyboard, stringing together letters that never form into a coherent whole.
So pretty much exactly like Norman Mailer, as far as I can tell.
