i know a lot of random facts about things, so in the middle of a conversation with someone i'll sometimes go off on facts about little details no one cares about and by the time i realize what i'm doing i've ruined the mood of the conversation cause now they're annoyed/bored
when i'm talking to a stranger and their chain of dialogue doesn't match the chain of dialogue that i've rehearsed in my head for talking to strangers, i get really nervous and start stuttering and saying stupid stuff and/or lying for no reason. the worst thing is when my brain just shuts off in the middle of sentences and i literally can't think of any words to say so i just clam up and stare at them really awkwardly. i also tend to start oversharing for some reason
while in public, i frequently become hyper-aware of my arms and legs and forget how to walk normally so i have to dedicate all my focus to trying to walk like i think i normally walk. this tends to lead to me passing my intended destination or going in the wrong direction
when i'm talking to someone with a thick accent, my brain starts forcing me to mimic it and i have to try as hard as i can to suppress it so they don't think i'm making fun of them
sometimes in conversations i get stuck on a certain set of words and i keep injecting them into my sentences over and over and over
sometimes i will consciously relax myself and realize i was making a really ugly face and i don't know how long i was doing it
as soon as i begin to get frustrated i become extremely angry/hostile and all useful cognitive function starts shutting down. i have to step away for a minute or two to allow my sperg rage to subside before i can really do anything
