Mask wearing doesn't appeal to me. My auditory processing isn't great and masks are a double whammy of muffling the sound and removing lip reading and expression. I also get overwhelmed by humid air (at swimming pools it tips my claustrophobia theshold). Fortunately I can't see myself entering an environment where it would be strongly advised at present.
It really wouldn't go down well with DS1 who functions with a lot of masking. He struggles with fancy dress type stuff, especially Halloween because he can't manually read through social cues to cope. Plus there's the sensory side of it for a child who can't cope with trousers or even things like tucking his hair behind his ear.
You'll be able to spot some of the avid mask dementors if they're not hot on their suncream, they'll be the ones with tan lines over their noses and mouths by the end of the summer.
Wearing one in crowded places where social distancing is trickier, I see the logic. In a great park where everyone is well spaced, it is rather pointless and odd looking!
(And what is it with the car drivers? Some of those would be far safer to brush up on their driving skills from some of the ones I've encountered in recent weeks!)
