My main issue is the laissez-faire approach we're taking. To an extent, want to do things that just affect you and other consenting adults? Knock yourself out. It's when it affects others as well... and it seems mental to me that we haven't at least taken measures to flatten a curve, and maximise the chances of no lockdown. Government advice is still to wear masks, meet outdoors if possible etc... but they won't compel the masks. When it comes to trains, shops etc it's not exactly an infringement on liberties or fun to wear them, and it's a bit of a bummer if you're vulnerable / worried to have others inflicting a, maybe not unsurprising, attitude of not wearing masks. As somebody mentioned, some think it's over, they don't need to worry... and government is heavily responsible for that.
Mrs. Wisdom for example, is now going back to her office, via trains and public crowded spaces including heavily socialising teenagers and early 20s, not because she needs to for her job, but because they want to give the impression of normality... and that's stupid.
At least let her make the choice whether she's comfortable in such environments.
