1. The couple had an unplanned pregnancy.
2. The city's zoning laws deemed the house illegal.
3. The builders didn't research how much it would cost to build where they did, and then the wireless internet they were counting on changed so it no longer reached the house.
4. Living in isolation was too much. Not a word said about how the house was too small.
So bottom line, these things can happen to any size of house. This is hardly an indictment on the entire movement.
