ET- Stream Nap

He walked until he came to a little stream, and he sat down beside it. The sound of the water was enchanting, and he put his head into it. He stayed this way for hours, listening, listening to the artery of Earth’s blood running. He fell asleep finally, head underwater.
...

Looking back over his shoulder, he saw three figures seated in it, all of them looking intently at him. He cut sharply into a narrow passageway between two houses, shook the car, and headed for the hills.

  He found E.T. head-down in the stream. The old voyager did not look good, but he insisted that he was fine, he’d only been listening.

  He gestured at the stream, at the sky, and at many things, but to Michael he seemed pale, and his footstep slow and heavy.
