I'm not describing what I meant very well, sorry. I'm not thinking of someone who needs personal care, I'm thinking of people with additional needs who just need a bit of extra support with life admin and navigating food shopping and things like that - I've seen charities who provide volunteers to help in that capacity.
I know what you mean, I just can't see Jack being that person.
Back when my dad was still with me, a lovely guy called James, the son of one of his neighbours organised a weekly thing whereby the more abled among us visiting the street (more accurately cul-de-sac) would do the shopping for all the frail old residents. Splitting BOGOF offers between them and bulk buying and splitting random things likes bags of cheap onions etc. It went from like 3 of us to 7 quite quickly.
It was like a little military operation with the best price offers being collated and chosen between the local supermarkets and even smaller places like the premiere shop etc.
Was always a lovely feeling handing a box of groceries over with more change than the recipient expected and being perpetually force fed digestive biscuits and cups of tea every Sunday afternoon.
But and this is where I get back in topic, this would never occur to Jack.
EDIT: Has been a good few year since this was a thing for me but even still, if I was the medias queen of thrift and charity then that is where I would start.
Community means more than charity to those in real need.
