Maybe I can't shake those romantic images, or maybe holing up behind closed doors feels like being a child exiled to my room as punishment. For whatever reason, I write best in the more central rooms of the house, the ones where I spend time doing many other things.

I guess you could say once you start working from home you can't go home again. It's the truth -- I shudder to think of all the inappropriate behavior I would get slapped around for were I to show my face in an office.
