Like, okay, hold on
You spend your entire life looking through your own eyes and moving your own limbs. You never see your facial reactions. You don't see how you walk, you just feel it.
So you make a couple of the same gestures and faces in the mirror that you did with other people to see if they look weird
BUT THAT MAKES IT WEIRDER
Meanwhile you're freaking out wondering if people feel the same way about their own emotive physicality
And you make a funny face...
Because nobody can see it.
And it's just for you.
Huh.
I sure hope I sleep better tonight.
