Yeah I can understand that Fred. At least you can call her and talk on a regular basis.
This is when it gets tough but you do what you can making sure she's comfortable from a long distance. We just had a long time friend of the family die on Tues. Known her since xmas of 1957. She was the last of a group of English friends I grew up with. She had Dementia and 86 but had a great life. Sad to see the older people pass on.
