It's so frustrating for everyone involved. I can understand not wanting to have to make a different plan or move out of my house--but I do think it's better to do it before you stick your children with the responsibility of deciding when you have to go. But sometimes the point comes and goes and you're not even coherent enough to know it.

Another elderly friend of mine stayed in her house with macular degeneration probably past the point of safety, but let her son who helped her know she understood if he couldn't make it every day and if something happened it was acceptable. She did fall and spent a horribly long night on the floor, which sent her to the nursing home, but she was only there for a few months and then died because that fall started a physical decline. Nothing you could plan, really, but I respected her for letting her family know she would forgive them anything.
