I don't know. Sometimes when I feel about to cry, it often evolves into an impulse to almost laugh. That must have been how I really felt at the time, because I laughed, almost giggled.
I remember my friend Johnny von Neumann used to say, 'with four parameters I can fit an elephant, and with five I can make him wiggle his trunk.'
我不相信幸福的结局,我相信真实的结局。
