I've developed an interesting perspective towards mask wearing over the past couple of weeks. I had been in Germany and flew back to England the day before freedom day. So for the first 5 days I wasn't out and about too much; only the legally permitted exemptions to my self-isolation for arriving from an amber country (which had an infection rate one fiftieth that of the UK but that's a separate issue!).
On my fifth day back (a Friday) I did test-to-release and got a negative result that evening, so went for a night out to a crowded bar. Zero masks, totally normal, absolutely fantastic evening dancing away as if the last 17 months never happened. The following Monday I did my mandatory Day 8 test and on Wednesday morning I got an e-mail to say it was positive. Almost certainly I caught the virus in the crowded bar.
So I've been self-isolating ever since apart from a few trips out to get food (legally permitted by my reading of the legislation, since I live alone) and of course I wore a mask, stayed well away from other people and used the self-checkouts at the supermarket.
But my symptoms have been so mild (nowhere near as bad as a normal cold) that I'd have never thought to get tested if the Day 8 test hadn't caught it. And it's given me a new perspective on mask wearing in places like shops and public transport where people might not really be there out of choice - at the very least, I can understand the viewpoint that it shows respect to others to wear a mask as it's genuinely true (from my own experience) that you don't know when you might be contagious.
But a further point worthy of discussion is that of course that assumes, that there will be negative consequences for anyone who is exposed to the virus. But certainly this is false for my experience (exposed the day after my second vaccination dose, negligible symptoms, feel totally fine). I think there should be a lot more debate around this point, i.e. how bad are the consequences if you're exposed to a person contagious with the virus, as it has a big bearing on the "respect" argument.
