I don't need anything, but our local FB page has a spin-off for people on their own or those who care for isolated people. I think the (county) council sorts out deliveries and so on for those who need them, and the local (town) councillors are doing things, too.
There are so many people here who are very quick to shout 'What part of lockdown do they not get?' though, that I for one would be very reluctant to knock on the door of someone I didn't know in case I got squirted with sanitiser for my trouble.
Pizza deliverers have been reported for being too near the door when the customer opened it, supermarket staff must wonder why they bother going to work, and every other thread on the local FB page is criticising someone for 'breaking the rules' when what we have is, on the whole, advice. That sort of thing doesn't foster a 'we're all in this together' feeling.
I have been indoors since the start of this, as has my daughter in another area. She is also vulnerable (although she is on the list and I am not), and despite the fact that she is only 26, she has had regular calls asking if she needs help with her shopping. She has said no - her boyfriend does it or they get a delivery - and that it would be fine to take her off the list, but it hasn't happened. She is working from home, and managing fine, so there must be others who need help more than she does, but the council seems determined to keep an eye on her.
