The world is surrendered to winter.
It would seem illogical that a freelancer should suffer from cabin-fever. We live and work at home, after all. We're not used to going out every day.
But I find that cabin-fever happens. It's not that we actually go anyplace really, since we work at home. It's just the freedom to do so is made more difficult.
I think it's because this blanket of snowfall has covered over everything. Skylights are muffled shut, the grass is buried, sounds are muffled. Almost no one even goes out.
