After the doctor told him not to drive because of his Alzheimer's he gave me his key. My big mistake is I put the key on my key chain. When I was asleep he took it back off my key chain and won't give it back. He was very upset because I didn't take him to the store when he wanted me to. I didn't know he wanted to go to the store. He said he will just drive if he wants to. Of course I am not going to wrestle him for it. No brothers or sons to back me up. Any ideas? He doesn't go to church.
