There are times when we can feel destiny close around us like a fist around a doorknob. Sure, we can resist. But a knob that won't turn, a door that sticks and never budges, is a nuisance to the gods. The gods may kick in the jamb. Worse, they may walk away in disgust, leaving us to hang dumbly from our tight hinges, deprived of any other chance in life to swing open into unnecessary risk and thus into enchantment.
