vegans rock- you're absolutely right. The Cummings rule to follow your instincts, supported by the Johnson advise to use your common sense is now what passes for government advice during this pandemic.
The official guidance must be confusing because every facebook group, forums like this one and radio phone ins I've heard are full of questions like, can I look after my grandchildren. I know I can't look after mine because Im over 70 and take immune suppressants. Well, I could resume day care and would love to but, at what level of risk? The children are considered not to be super spreaders. They are at school and nursery two days each week, their parents at work. They have begun to see other family members and to meet up for walks with close friends and their children. The idea of a safe bubble is a non starter for most of us.
