Oh yes; yes, they do. But I am largely a collection of brain symptoms bound up in habits, encapsulated by words. Lots of words. I’ve found, once the habits are well-formed, more or less the way I like them (work in progress, here), and one of the habits is playing with the words, the brain symptoms give me little gifts; wee shiny objects, all glittery and fine. And I play with them, with the words.
