"Closed" families have a tight boundary around them that separates them from the outside world. You don't just drop in on a closed family. These families exercise power in a top-down way, with the father customarily the "boss." They value preparation, unity, sincerity, and clarity. Open families, by contrast, have a less formidable barrier around them and tend to value tolerance, authenticity, latitude, and responsiveness. Random families are dramatically different from closed and open families. Their use of time and space are likely to be dispersed, irregular, and fluctuating. They value ambiguity and whimsicality; above all, they want to protect the originality and creativity of their children
