Thanks very much for the replies.
With regards to them calling around to the house, they are a major lifeline for me as they bring food (cooking anything complicated is hard for me, so they are bringing ready cooked meals, etc., as well as shop bought items) medicines I need, etc. We are operating an ‘exclusion zone’ whereby they don’t enter the house & stay 2 or 3m away from me outside, plus anything that is coming from them to me is cleaned, I wash my hands & so on & so on!
I hope that clears that bit up – I probably should have mentioned it in my original message!
