A friend of ours loves to tell the story of her grandfather's funeral. Her grandparents lived, for the most part, on the income from a trust set up by his parents years before. The trust stipulated that when her grandfather died, her grandmother would get the same income, and she could stay in the house. There was a condition, though: Her grandmother would lose everything if she remarried. Well, then, she said, I'll just have to shack up with the guy.
