“To allow yourself to play with another person is no small risk. It means allowing yourself to be open, to be exposed, to be hurt. It is the human equivalent of the dog rolling on its back---I know you won't hurt me, even though you can. It is the dog putting its mouth around your hand and never biting down. To play requires trust and love. Many years later, as Sam would controversially say in an interview with the gaming website Kotaku, "There is no more intimate act than play, even sex." The internet responded: no one who had had good sex would ever say that, and there must be something seriously wrong with Sam.”
