The not-wearing-masks bit feel more clear. I have always viewed it more of a matter of modulating one's personality to fit the appropriate occasion than necessarily wearing a mask, though. There are times you are truly wearing a mask - when you are not presenting yourself truly at all - and other times you are simply a less (something) version of you - less exuberant, less foul-mouthed, less inebriated, whatever.

I think we are different people. Who I am to my parents isn't who I'd be to a partner and it doesn't necessarily have to do with wearing a mask.

I certainly have friends I can be very weird around and I appreciate that and they are my favorite friends. I get that idea of "not being constrained." But who you are has as much to do with your ability to modulate your personality (otherwise you become obnoxious in the wrong situation) as who you are when you don't modulate it. Are you unable to control your emotions? Do you control them too much? Do you sometimes rage like Alec Baldwin or do you react by not reacting?

I don't know. Just theories.
