There was frost on the house roofs this morning. This would not be so bad except that, in the interests of saving money, we are attempting to turn the gas furnace off for the year. (So far DOB has managed to turn the gas off, but the instructions are inadequate as to how to get the pilot light to stop burning. It's better than the other way around.)
Also in the interests of saving money on the more common warm days (not to mention the freshening of the air in the back bathroom, which the former owners very imprudently carpeted), we generally have some windows open. Sometimes they don't get shut soon enough.
We did manage to get out of the warm bed soon enough not to have to test whether the savings in energy were offset by the costs of being late to work.
Alas, I don't even have a big pile of dishes to wash while soaking my hands in warm water.
