This thread perfectly illustrates exactly what the problem is. People refuse to actually live in the situation we're in and take sensible, practical measures to drastically reduce their chances of getting Covid or anything else. They want to do EXACTLY what they want to do, at all times, like spoiled, petulant little children.
When I get on the train to central London, I'm happy I'm able to live my life normally and go out and do things. The open windows and being a bit chilly are a tiny price to pay for hugely reducing the chances of catching something, but no, for some people this is too much of a sacrifice, so they close the windows and force everyone else to sit in a germ box with the windows steaming up, because they couldn't be arsed to wear a scarf.
Having a birthday dinner at someone's home is about 90% of the experience of having it in the pub. The birthday person gets their dinner cooked for them (or takeaway ordered in), they see their loved ones, socialise, get out of their own home, but no, they just have to go to the pub and put others at risk because they want exactly what they want.
Having to wear a mask in a hospital waiting room is slightly annoying but a tiny price to pay for receiving healthcare and keeping others safe. But no, rather than tolerate a minor inconvenience, most people would rather just not wear one.
The selfishness, short sightedness and bullishness displayed on this thread is why we are where we are.
