So. The first set of home PT exercises: not much fun. I slept wretchedly thanks to the vertigo and my dear little beast, who decided that it was the perfect evening to be bratty. And when I went lurching down the stairs this morning, I noticed that the kitchen floor was cold. Really cold. Really, really cold. Like the air around me, in fact: cold. I checked the thermostat, and it was a good ten degrees F colder than it's set for. Attempted to poke the furnace from the thermostat control. No result.
It is a really bad idea for me to go lurching down the basement stairs at this stage of dizziness to see if we can poke the furnace into submission, and everyone else is still asleep. But in fact I'm not so sure there's going to be much we can do on our own anyway, so the optimal strategy may be to call and leave a message on a furnace repairperson's machine first thing and then to do my first round of PT exercises and crawl back into bed.
Edited to add: Wiktory! The furnace technician is scheduled to arrive at 9:00.
