a young man and an old man are talking

a young man and an old man are talking. the young man asks the old man what he has learned. "almost nothing is true," is the old man's reply. The young man is upset by this. The young man prays that night, asks god to show him something true. For a full minute, nothing at all happens around him. He sees letters appear above him, one at a time, in solid black letters. Eventually, they spell the words: "let's talk about something else."
