I struggle to see why I shouldn’t wear a mask in certain situations. e.g. the supermarket, where I’m not there too long, am hardly talking to anyone, it’s indoors with lots of other (unmasked) people. There are almost 0 downsides to wearing one in that situation (for me at least).

COVID is still killing a lot of people, and even if it doesn’t kill you, it sucks to get it. So yeah, makes sense to me to mask when you can.
