I've been told my quietness makes people uncomfortable, but telling people that they are being quiet is... supposed to achieve what? That's not a way to start a conversation, it just puts people into a defensive mode. How graceful!
I've been told I don't smile enough. I would be a poor comedian indeed if I went on stage demanding that people laugh simply because they paid for the seats like it's an obligation.
I have perfectly fine social skills. I just know what my priorities are, and I'm not willing to pretend you are one just because you'd like me to. I don't value that inconsistency.
