Every time my mom asks the questions about her house, she experiences surprise, shock, sadness and grief when we explain we are selling it. Of course she does not remember that we’ve taken her to see her home many times, even just a few hours earlier. We explain why we must sell it, we have photos to show her the process of fixing the foundation, flooring, etc. She always comes to a point of understanding and agreement but a short time later she’s forgotten and the questions and cycle starts over again.
Don't lie. Divert.
