Write about a fellow who has 3 sons, living together as a family, but his wife died sometime ago. Simultaneously, write about a mother of three daughters who recently lost her husband! And they get this strange hunch to get married, and move in together. The father could be an architect of some sort, and it could all take place in the 70s. And they need a maid, too, who acts like a second mother to the kids. And make them get into family-friendly antics over the course of five years, and then have them star in 3 more sequels that are neither as popular or critically rated as the original. :D!
