When you see me at social gatherings you would either label me as an introvert or an extrovert. It totally depends on the people i am around. Not like whether i know the people or not (i will happily socialize with strangers on the right topic), but rather what type of people and what the current topic is.
I deeply dislike small talk, or people i know (or at least i think) don’t share any common interests with me.
That’s why i am quite the talkative person at work but mostly quiet (and uninterested) in private.
