gamble is something strange

sunday , go to friend home. In there ,three people gather together,how to  kill time , one said :"let us play 'fight the lord'"
It is a poke game , need three people. loser pay the money to winer,the rule is so easy,the process is so tie. In the end , friendship may be broken. when I leave for home ,In the road ,I feel guildy,feel very bad , no ,this is not my way to kill time. I respect friendship,not want to do harm to it .So I decide to leave this game,maybe it means leave these friends until they feel the same feeling as mine
