I am always happy to hear from you. But please be advised that a reply is unlikely. Writing for a living consumes hour upon hour and requires elusive concentration. I have to be ruthless about sequestering those hours and parceling that concentration. Besides, I am neither a gregarious individual nor an engaging correspondent—there's a reason I've spend most of my adult life sitting alone, scribbling.
