Petra with whom I recently reconnected shared a video that gave me pause to think, not least of all because its captions were in a language I do not understand.  It appeared to be about homeless men who were hungry and jealously guarded a slice of pizza.  They each were unwilling to share any part of their meager food supply with a reporter posing as a hungry homeless person on the pretext that they were hungry.  Then the reporter gave a whole pizza to one of these men who was overwhelmed by the unexpected gift.  Some minutes later, his colleague came by and asked this man if he could have some pizza as he was hungry.  The homeless man immediately offered to share his pizza and then broke down in tears of gratitude over being able to offer another hungry person some food.
