However my instructor was and is brilliant, so I did not, in fact, forget everything I learned over the course of five years and had instead a wonderfully fun time learning some new stuff and being reminded of some old stuff. And Teddy was, as before, perfectly happy hanging out with D. I'll give it another week, and then switch to twice a week, subject to holiday weirdness.
In addition to clearing out my brain by having time to myself that was not devoted to immediate, basic, physical needs (like sleeping or taking a shower), I got to write, work out and plan a vacation. We're spending the last week of the year in Leavenworth (yeah, I know; the goal was Stevens Pass, to get up in the snow and above the clouds. This was the closest large mass of rental properties and even so most of them were booked already). D. may come along, which would mean R. and I could both go cross country skiing without worrying about the kid freezing to death.
