why, oh why. questions, answers, puzzles to be figured out. joy of joys, yet none of that. the riddler laughs in the background. cha-ching. me and dave, just like that. no choice. very much a choice. a decision. things coming to a head. the head. the point at which there is super = saturation. the tiniest seed crystal will completely precipitate the solute. if that's right. edges, bridges, parachutes and hang gliders. it's the ride of your life. and mine.
