I've been feeling this for a while. There's a performative sort of aspect to people's personalities now as though they are mimicking a character playing out scenes. There's always been jokers or people who quote lines from movies but what I'm seeing is way more pathological than that. I don't know if they are doing it on purpose or oblivious to it. If it were children doing this I wouldn't be too concerned but it's 30 year adults mimicking stuff like anime / video game style expressions and movements. I worry that something has gone collectively very wrong in all of our brains from over stimulation.
