Is this the secret reality of extroversion/introversion? I'll have to think about this for a bit but looking back at the encounters I've had with extroverts, they're mostly just good at smalltalk, jokes and BS. They can sometimes be fun but can also be extremely tiring to be around if you're not in the mood for that type of engagement. On the other hand, I know a lot of introverts who are extremely talkative when discussing their area of interest or any other deep conversation. I'll have to be mindful about noticing if I actually do get tired of social interaction the same way with "introverts" and "extroverts". Thank you for this new perspective.
Are you sure those people were extroverts? I am most definitely not an extrovert, but I'm fine with "smalltalk, jokes and general BS" when I have to be. i.e., if I'm trying to be sociable, or to meet someone, or just not be a party pooper. It's not my normal state, it's just me trying to not be an asshole.
