My friend greeting him, then went over and shook his hand. After they had talked for a while, my friend signaled me to join them, but immediately left me alone with the old man, not even bothering to introduce us. He was not in the least embarrassed. I told him my name and he said that he was called Juan and that he was at my service. He used the Spanish polite form of address. We shook hands at my initiative and then remained silent for some time. It was not a strained silence, but a quietness, natural and relaxed on both sides. Though his dark face and neck were wrinkled, showing his age, it struck me that his body was agile and muscular.

I then told him that I was interested in obtaining information about medicinal plants. Although in truth I was almost totally ignorant about peyote, I found myself pretending that I knew a great deal, and even suggesting that it might be to his advantage to talk with me. As I rattled on, he nodded slowly and looked at me, but said nothing. I avoided his eyes and we finished by standing, the two of us, in dead silence. Finally, after what seemed a very long time, Don Juan got up and looked out of the window. His bus had come. He said good-bye and left the station.

I was annoyed at having talked nonsense to him, and at being seen through by those remarkable eyes. When my friend returned he tried to console me for my failure to learn anything from Don Juan. He explained that the old man was often silent or noncommittal, but the disturbing effect of this first encounter was not so easily dispelled.

I made a point of finding out where Don Juan lived, and later visited him several times. On each visit I tried to lead him to discuss peyote, but without success. We became, nonetheless, very good friends, and my scientific investigation was forgotten or was at least redirected into channels that were worlds apart from my original intention.
