I don’t understand why people have to be told by the government or health advisors on what to do? Common sense is also an option. Take precautions, get your elderly and / or vulnerable relatives to take precautions. OAPs being in isolation doesn’t mean no one can go and see them, you can visit and take supplies. Be cautious if it makes you feel better, keep a safe distance, don’t hug / kiss etc. If you feel unwell or they do, don’t visit.
There’s simply no need for some of the hysteria that’s around ATM. Yes be worried, I’m worried for my vulnerable relatives, but be calm and be sensible.
My daughter says some of Sainsbury’s shelves are bare, specifically pasta and long life stuff. Next weekend they’ll be stocked again but this is of little use to people who literally shop day to day and can’t stockpile.
