The master was resting in his room on a hot afternoon when his disciple walked by and peeked in. “Please come in,” the master said, “I had the most wonderful dream. Would you like to hear about it?”
Instead of saying yes or no, the disciple left and return with a cloth and a pan of water and offered it to his teacher, who washed his face and felt immediately refreshed.
Then another disciple walked by and, seeing them, asked: “Can I come in?”
“Oh, yes”, the master said. “I just had the most wonderful dream. Would you like to hear it?”
Instead of saying yes or no, the second disciple went and made some tea and brought back the pot for them to drink. No one ever heard the story of the dream.
