Most importantly, best of luck with the chemo
@kevin horlocks wand I hope all goes well.
Secondly, and in no way trying to be disrespectful or anything here so I genuinely apologise if it comes across that way, only trying to make the point re covid. I know there's been very little that you and people in your position can do to protect yourself at any point of life, and I know that many in your position wouldn't dream of asking for restrictions at any normal time.
Where I think this is different is that we have an ongoing pandemic and case rates are heading to potentially the highest that they've ever been in this country so transmission is high and people in your position are at perhaps more risk than previously, which is why I support masks at least for the basic aspects of life - shops, transport and supermarkets.
I realise we can't *always* restrict the vast majority for the few vulnerable people, but in times of such case rates I think it would be the sensible compromise until such time the case rates are under control.
Pubs, football, gigs etc are a bit different as they could be seen as luxuries to varying extent which is why I only stipulate the more basic things in life where I support mask wearing continuing at least for the time being.
