1) True. I went out for my company's Christmas party a few days ago and my CEO actually made a remark about how I never smiled in the office but was smiling and in the mood during the party. I can do this but just not for very long which may be why
I could be mistaken for an introvert/shy, but people often realize I'm not after minutes of talking to me. This makes people believe that I must hate them and that's the reason why I don't bother to engage them more regularly.
2) I'd say my sense of humor is more dark than cerebral/witty. I don't smile so I don't think I come across as friendly, but people have made comments about how I come across as a gentleman.
3) Yep, I can only do this for so long before feeling the need to either disengage from the group or talk about something more interesting rather than formalities and small talk.
4) Most conversations I have that last longer than about 5 minutes turn into a debate or an exchange of interesting information.
5) Yep. When I'm not in my "fuck the world" mode, I'm told that I come across as someone who is well spoken and polite.
6) Yep.
7) Covered this in 3) and 4).
8) I don't trust anyone and I am highly argumentative.
