An 87 year old friend of mine recently moved from a house she lived in for 40 years. Her husband died of dementia 10 years ago and she'd been living alone since then. Her health had declined to the point where her son felt she needed to move to a location closer to him. Her whole family joined in to help get her moved and get her settled but they pretty much left her out of the process. This happened months ago and she still hasn't been able to find her notebook that she kept all their addresses and phone numbers in. This has been very difficult for her and didn't really need to happen. Also, many of the other things that she treasured and would like to have at her fingertips have been put in storage and buried so deep that nobody even knows how to find them.
A bit of forethought and understanding of her position by her family would have made that transition a lot easier for her.
