I wrote a reply but the server ate it when rebooting. Much more succinctly now, a guy I knew and myself, circa 94, did experiments where we'd be really matter-of-fact with people and then throw in something totally ufology, very serious about it, then drop it and change the subject. People would hedge around us, looking for a time alone, and end up confessing the most amazing experiences when nobody else could hear. Something about being a really practical personality and then putting this stuff in the same 'acceptably logical' model, even for a moment, often really cracks people and they just can't wait to pour it out.
Speaking of UFOs, LD just posted this in my private forum, so hilarious!
