I realize this is ad hominem, but when I used to live in the west village I would see him all over the place in the middle of the day, working, but notably not in an office. It was A Thing. I would see him (frequently, he was a fixture of the Joe's on Waverly in particular) and with envy think about what a great gig he's got, that he had the freedom to work wherever he wanted. Reading about him literally tear up at the thought of all those empty desks in all those empty buildings across Manhattan is hilarious.

I also happen to have it on good authority that when he did show up to an office he would arrive, and I am not making this up, in pajamas.
