I didn't have a room growing up, not as such.
My father invented a thing, a space and time thing. I don't know how it works. To listen to him try to explain it to people, he doesn't quite know how it works either.
I slept out on the Serengeti, so long as I could show Mother that no predators would pass by my chosen spot that night. I slept in a crook halfway up a Sequoia, after I'd shown Father I could secure my bed to the trunk, and myself to the bed.
Better than a room, I think.
