I'd been nervous the night before, to the extent of picking out an outfit before I slept, sleeping badly, and then fussing excessively over minutia while getting ready. But by the time I arrived, I was calm. I'd had a leisurely ride over the river in fantastic weather. I wasn't worried. Why should I be? I knew the topic at hand: I had, and was still, living it.
I gave the capsule summary of my life, carefully explaining exactly what perspective I could offer, and what I was certain existed but had not experienced. They asked questions, and I answered. I was utterly transparent. The meeting was "off the record", but I can't imagine I'd have been more reserved even if it wasn't. I could imagine a couple of the questions making someone uncomfortable. I am not that someone.
My friend, who had arranged the meeting, sat on the other side of me, a couple times offering questions which may have helped lead them to things we'd all not considered. At the end, I regretted only one thing. The question was not an unfamiliar one. I'd considered it repeatedly for years, and still had no answer to satisfy my scientific desires.
