Sometimes they just don't like to admit they need help. My F-I-L is 86. He insists he can still climb the ladder to pain the side of the (2 story) house, no matter how many times I till him I would be glad to help. Helping family isn't charity, but he still says he won't take any unnecessary risks and he's fine.
I tried to make this all about Charlie and my concern for his knees, not to put unnecessary strain on them, and so on, and he seemed OK with that. Not to mention the fact that he was surprised that I was able to rassle his now discarded bed out of the apartment and onto the patio.
In my secret other life before retirement, I ran a furniture repair company and was used to schlepping sofas and other items around and jostling them into the back of a cargo van. He was impressed. *meh*
He was complaining about his phone’s battery and I told him to let me know in the morning so I could order him a new battery before I leave. THAT is charity!
