Laughing Boy

Two employees were working in the basement. One fellow heard a little boy laughing. He went into one of the rooms in the basement to see if anyone was there, but didn’t see anyone. A short while later, he heard the laughter of a little boy again in the same room. He went back into the room, and again, no one was there. He mentioned this incident to the second employee, and the second employee told him he had experienced the same thing three days earlier.
