Dude it happens. If we never had nights like that, none of us would be working whatever job we do. One of the other posters said it was god's way of punishing us for thinking we finally figured it out. I can relate to that in both pool and golf. Both games are played "One shot at a time". When the shot is over think to yourself "Damn sure glad that's over with". Then resign to yourself that you'll do better on the next shot if given a good oportunity for a shot. Next shot will be better, guaranteed.
