why so cold?

[mellowtigger]

I woke up this morning wondering, "Why am I so cold?" I have the bed's heating mattress set on high, even though the temperature outside is only at freezing (well, 2C/35F anyway), but I'm still cold.

The cat demanded food, so I went downstairs to feed her. I checked the house thermostat. Ah! The batteries on the thermostat were drained, so the furnace was not running at all. I put the batteries in the recharger, but I have no AAA-sized batteries right now that are charged. It will be hours before I can get even a temporary respite from the cold.

I went back upstairs and checked the thermometer (the CO2 meter) by my bedside. It's 12C/54F in my bedroom. That's why I'm so cold this morning. Problem identified, and the fix is on the way.

P.S. The cat finished her meal, came back upstairs, and clawed her way under the sheets in my bed. I turned the heating mattress back on for her. I'm at my computer, wrapped in a thick bath robe for warmth.
