I remember watching Great Grandma  get mad at other people.  When I would visit her to play Rummikube she would always get so angry at Ray.  Because Ray would not put down his tiles until they all played.  And we would sit there for a very long time since none of us could play because he was hoarding all the good ones.  Great Grandma would go through a process.  First she would stare at Ray with angry eyes.  Then after a few more turns she would start trying to hit him on the arm.  Then a few more turns would go by and she began to coax him adamantly: "Play your tiles, Ray!"  More turns would pass and she would declare "Play your tiles, Ray! We know that your tiles play!"  Ray would calmly inform her that he was going to win and he was going to wait until he was ready.  
Then Great Grandma would get vicious.  She would turn to me and whisper: "This is why no one else likes to play with him."  I would try to broker peace between them but it was no use.  Ray would continue to hold his tiles close and Great Grandma would get more and more abusive about his unsportsmanlike conduct.  Finally, just when the tension became unbearable, three linked incidents would occur.  First, Great Grandma would start throwing tiles at Ray.  This would force Ray to begin to play one or two in order to appease the monster she had become.  His action would of course allow me to go out.  And having won the game I got to choose a new one, like Cribbage, where you could win without relying on someone else.  
I thank Great Grandma for that lesson.##imported-begin##Darrell Miller##imported-end##
