“Trust me, it was a lot of work. But in a way, those were sort of the start of all this. No, it was as your wife said. A spark started it. A literal one, awhile ago, when I stuck two wires to a chunk of quartz and asked her to squeeze.” You can’t help but laugh at yourself. “It was such a stupid little thing. We had no idea what we were getting into, in more ways than one. I can only hope that whatever I leave behind for her is as magnificent as that first moment was silly and trivial.”
