When I lived in Hawaii we had a three bedroom townhouse for a family of five. The townhouse next door, which was the same floor plan, was owned by three sisters who lived there together. They had two husbands, their mom, and some number of children in various sizes. Most evenings they were out on their lanai playing guitars and singing together...not all of them, just different combinations. Collectively they were probably the happiest family I've ever been neighbors with.
