Isn't there something you've done in your career that you take enough pride in that you'd enjoy explaining it to people who would appreciate it (not including that time you gamed an interview)?
I don't enjoy doing anything with other people, but it's a necessity given that we need jobs to survive. I could be happy just hacking on something in a basement and never talking to a soul if I could. I can wear a smile if you need me to, but I definitely wont mean it. Sorry.
