Introvert social fallacy #1

Lots of introverted people believe in the existence of "idle chit chat" or "pointless small talk" because they don't realize that it serves a purpose. If you are sensitive to body language, vocal tone, and a person's choices in prosody and grammar, then how they are saying things can relay a lot of information that they are not directly saying.

If you see me listening without making eye contact and not engaging in much conversation? Something is up. Building a baseline for the standard conversational behaviors of your social circle is part of relational information and social policing. Knowing when something is wrong and what you can probably do to fix it is important knowledge, and there is a reason why most introverts are socially awkward: because they aren't paying attention. Without that extra information being conveyed, they are lost in a sea of potential responses with no lifeline.
