A longish day working from home
I've been working from home all day, taking care of a very sick Colleen and ripping stacks of CDs. (The latter, especially, give me a convenient way of timing my breaks and an excuse to come out and interact if anyone's in the living room.)
Without the usual workplace distractions and most of an hour's worth of commute, I've actually been pretty productive. Even without working hardware, there's a lot of planning and documentation I can -- and did -- do just as well running Emacs at the other end of a net connection.
