We often regret having prolonged the game (to the private glee, we feel, of a few players who led us on). It would have been better, we always realize too late, to have left too early. If we had left earlier, we would have then been tormented by the question of whether we should have stayed, but having lost too much right now is definitely worse, with the last hour having been a grueling experience. What’s worse, we can’t really say why we have stayed too long and so we are likely to repeat the same mistake when next time we inevitably show up at the table.
