My thoughts are with you. Had to do the same with my grandmother a few years ago. She now lives in Florida near my remaining uncles (my dad passed over 20 years ago) and is polite to me when I call her but I don't think she remembers my name.I have to drive to Ohio this weekend to meet my brother so that we can take our Dad's car away from him. He is 86 and no longer competent to drive. It will be sad for him but he knows that it's coming. We spoke of it recently and he remembered having to do the same thing with my grandmother. Life moves in a full circle and is filled with irony. I will always remember the first time he let me borrow the keys to his car at age 16. Now, I am taking the keys away from him. Not that many years ago, he was a whiz with a computer and an outstanding amateur photographer. Today, he can't even operate the TV remote.
