They’re, ah, demos: demonstrations of stuff? A hour’s worth of fencing, heavy weapons fighting, dancing; a couple of tables of various stuff and people standing around explaining things. I was one of the people explaining things.
It was fun, but surprisingly tiring. I am out of the habit of adulting with other adults around. It’s not nearly as bad as it was several years ago, when I discovered that I had virtually forgotten how to talk with other adults, thank God. But it’s still not as easy as it used to be. Which is, of course, an excellent reason to do it. Fortunately, the SCA is full of people who don’t get upset when you admit that you’ve run out of social interaction, because we’ve all been there.
