I stood in the back corner watching them. They resembled three veterans who had met once more on a cold day after years of separation, and had lit a fire to warm themselves. I had pricked up my ears to overhear what they said, but none of them opened his mouth. You felt the air between them was vibrating and that a string of unspoken words was being unwound from mouth to mouth. Without the slightest doubt, this was how the angels spoke in heaven. How long did their silence last -- how many hours? It seemed to me time had come to a standstill, that one hour and one century were of the same length.
