What a concept.
Sorry, but my wife is the biggest divider. She actually pits the kids against each other. (Very long story. Short version-she needs counseling for things that happened in the past, but does not acknowledge that she does.)
I'm going to encourage the acquistion of a new house, be it the hobby farm or something else. Large enough for TEMPORARY visitors, and far enough away that the kids would not want to move in and commute (40-60 miles/1 hr drive - here in MN that's a significant drive. Avg is 20 min.)
