She was very relieved to not have to worry about money.
If anyone is trying to deal with this situation, I would recommend bringing up the thought of how much effort it is to keep up with your money. That might be the key issue.
Back in Dec 2009, despite my Dad's clear dementia problems, he adamantly refused all assistance. He didn't want our help, he didn't want paid help, he didn't want to waste any more time on doctors, he especially didn't want to do POAs. He made it another 14 months but, judging from his bank and his credit-card records, his mental acuity declined rapidly during the 15th month and he ended up in the hospital ER.
During the week I visited him in the surgical ward, he just wanted to leave. (Hard to blame him for feeling that way.) When I brought him a suitcase of clothes & toiletries, he decided he was on a business trip and kept packing to check out of the hotel and go home. (Which got him labeled a "wanderer".) He couldn't even remember how to operate his CD player, but he wanted to resume his independent life and be back in charge of things. Every time I brought it up his resistance hardened, so I just kept changing the subject.
On the day before he was discharged to a skilled nursing facility, I brought in the utility bills with (filled-out) checks for him to sign. When he saw how quickly we got through the pile of paperwork (hey, I'd had a tour on an admiral's staff) he broke down in tears and said that he'd been having a terrible time taking care of his affairs. When he got to the SNF and realized that they'd prep his meals and do his laundry, he decided that he would stay there for the rest of his life.
I think giving up that control is so hard that most parents don't even know how to do it. But when they do, the relief is immense. The trick is helping them get over that first hurdle of accepting help.
Nope, haven't had a bank or anyone try to sell me an annuity.
So to the bankers you don't look old enough, inattentive enough, or presbyopic enough...
