People hear and perceive exactly what they WANT to hear. This was illustrated by a speaker trying to convince a group of alcoholics the evils of alcohol. On the platform he had what appeared to be two identical containers of clear fluid. He announced that one contained pure water and the other was filled with undiluted alcohol. He placed a small worm in the container while everyone watched as it swam around and headed for the side of the glass, whereupon it simply crawled to the top of the glass. He then took the same worm and placed it in the container with alcohol. The worm disintegrated right before their eyes. “There,” said the speaker. “What’s the moral?” A voice from the rear of the room said quite clearly, “I see that if you drink alcohol, you’ll never have worms!”
