Oh, yes, @strangeling, I’ve often wished that I had a closet full of robotic Doppelgängers like Superman’s to do the things I don’t want to do, like go to work and go shopping. Unfortunately the usefulness breaks down when it comes to keeping medical appointments or traveling in my place. No good solutions for those yet.
At my house people can pretty much have time alone whenever they want it. Sometimes one of us will actually say “I’m just feeling kind of out of sorts with the world today, so don’t take it personally, but I’m just not going to be very good company.” Everybody respects that.
Those days are most likely to be online days, writing days, napping days, or a combination, no matter which of us it is. Sometimes there’s some vigorous yard work instead. Usually things settle down in less than a day’s time.
Causes might be found in natural rhythms and cycles, but also sometimes it just plain feels as if nothing is going your way. That shift from reacting as the baby that can’t stand to be thwarted back to being the grownup who deals with setbacks and adjusts expectations and figures out what can be done to overcome disappointments can take a little self-focused, soul-gathering down time.
