Solution: for every room I sweep, and every room I mop, I get a glass of mead and some internet time. This encourages me to finish each room, and to take a rest break afterward. On the downside, this means after a few rooms, I've really lost all motivation to get up out of this chair and go do another. On the other hand, I think the injured limb is about done for the day anyway.
Now for a very weird fact: did you know down here in the south, land of 8 inch long pine needles, they bundle those pine needles together and sell them as "pine straw bales"? My mind, it is well and truly blown. According to the gent who showed them to me, as well as gave me prices for renting a tiller, "They're mostly used on flowerbeds, ma'am. The birds will also steal more of the wheat straw for building their nests."
It's a whole different world down here. I'll think I've got a handle on the culture, and then I stumble onto something like that, where "everybody knows" but a transplanted Alaskan.
P.S. J. R. Shirley - Lydia Bailey is on the way. Thanks for the recommendation!
