The thing is people DO need the Govt to say no:
My 73 year old mother who thinks she's immune
My father in law in his 80s, who wants a bargain break
My boss who takes non necessary trips to massive conferences in London, who goes to the Liverpool match, who is travelling to an infected country and doesn't want to self isolate. Who thinks it's a joke but won't suggest WFH.
If the Govt said that mixing in crowds, socialising, travel, employees working in the office when they don't have to, non essential travel, was to be avoided then maybe lives could be saved, but apathy rules as it comes from the top down.
If we survive this then I will have a long memory and so will my children - future voters.
