I heard an interesting story once about a poly couple who had several kids. Sometimes the man would look after the kids while his wife was out for an all night date with everything included in the company of an exciting stranger. Other times it was the other way around. When the children asked where the other parent was they where told "Mommy / Daddy is out on a journey". The word "journey" gave rise to thoughts of fun and adventure and discovery Which was not so far from the truth. As the children got older they were told about the benefits of freedom to enjoy quality time with different people as long as honesty and respect is maintained. Therefore more details could be revealed without harm to the psychology of the children. In this way the family delevoped trust and open mindedness in their relations. Over time they learned more about freedom in relationships based on quality time together instead of ownership with fear of losing control. I am not sure if everything was as rosy as it this but the story does make me smile :)
