That could be just so true Dave. I automatically delete an awful lot of emails I don't recognize and all spam without reading it. Been doing it for years and it hasn't had any effect on my life as far as I know. I also don't have a smart phone so if I don't crank the laptop up for a few days I wouldn't know anyone had been trying to get me. We've also taken SKY's call blocker as it was offered to us free when we renewed our broadband last Christmas time. We used to get shed loads of scam calls - you know, "This is microsoft technical department wanting to sort a problem your computer has notified us" or " This is Amazon with details of your free Prime account, If you can just give us your bank account number we'll activate your free account" and many more. Now we really don't get any at all so it will probably block these ones you are talking about. Sometimes it asks us if we want to talk to the person calling, all we have to say is No, and it permanently blocks that number (unless we chose to unblock it).
It seems that people could be asked to isolate multiple times too. It also occurs to me that the people who test positive may well be working in an environment where infection is more likely so these people will be being asked to isolate again and again. Not many employers will be able, with even the best will in the world, to operate a business in this way, guess who will go?
Revenge reporting might be a very real risk too, as will "forgetting" to report friends who you know are really scratching to make a living.
The big problem I think is that all these high flying, well off, powerful people down there in the enclave called London really don't have any idea what life is like in a Glasgow tenement or back street in Newcastle or hill farm in Cumbria. We've had a number of examples of them just lately haven't we? They are not worrying where the next meal is coming from, or how they are going to get the bags home from the food bank, or when they are going to get their pitiful universal credit payment. - neither, thank god, am I, by the way, but I'm nearer to seeing the problem than them high heid yins.
Oh, and by the way, please don't tell Mrs J about Karen will you? It's cost me a fortune in bribes to keep her secret all these years!
