Maybe you don’t see the social and communication value of seeing someone’s face, I do.
Maybe you don’t live somewhere where the temperature is 30 degree Celsius plus often, at which point wearing a mask is a very different UX to colder weather.
My summer was 40C. It's ok if you find it uncomfortable. Not everyone does.
From communication point of view, I do care and want to normalise wearing masks whenever you want. I'm totally using one when I need to go shopping and not feeling great.
