She was autistic, and they spend a lot of time in their heads. Probably why she was trans as well - thinking about things too much and wondering why she didn’t “fit in”. (60% of girls that transition to “boys” are on the spectrum for autism and other mental issues).
Or - maybe she was like my old man. “You know - half the fun of taking a big trip is planning for it! Look at this map, we’re going to land here and then....”
Well, at least I can say I’m a better planet than she is.
