The subway encounter

Jane and her son boarded the subway train and found a seat.  It was mid afternoon, and the car was nearly empty.  At the next stop, the door opened with a whoosh.  In came a middle aged man, dressed in possibly every piece of clothing he owned, carrying a box.  Jane and her son looked at each other, eyebrows up.  The man sat the box on the bench opposite the door, jumped back and shouted “Whoa!”

Nothing happened.  After several moments, the man started a strange dance �" part twitch, part bounce.  He seemed unaware that anyone shared the subway car with him as he began talking to the box in unintelligible tones. 

Jane and her son left the train at the next stop. They stood on the platform watching as the doors closed.  The dancing man, suddenly still, turned and looked at them for the first time, tears streaming down his cheeks as the train pulled away.  At the top of the stairs they heard the blast.
