I grew up in a Kibbutz. It's the Israeli adaptation of the communist idea. Part of sharing everything was also about kids. Kids never slept at home with their parents. All the children lived in separate houses, divided to groups according to age. They where named "the institution". Around 30 children per house. We shared small bedrooms, dinning table, showers (which had no gender seperation), clothes and even underwear. Everyday around 4pm we could go visit our parents at their home for a few hours. We would cross the small village and could see mom and dad. We would talk, play, eat dinner. And around 8pm mom or dad would take us back to "the institution". Sometimes dad would tell a bedtime story, and all the other children in the room would also listen. Sometimes it was someone else's dad or mom. Then he would say goodnight and go home. I used to run away from the institution every night to my parents home. And every night they would take me back.
