This situation came up in our household in a rather unpleasant way. My husband's mother, who had been widowed, was ill and could no longer live on her own. I said, without hesitation, of course she'll live with us. When we bought the house we currently own, that was part of the consideration, although we didn't know the circumstances at the time, we just knew there could be a possibility of her living with us sometime. She lived with us about a year until she passed on. It was a very special period of time in many ways. She and I got to know each other in a way we never would have.
