People think you have to be either extroverted or introverted, but I'm both.
Hmm, I disagree, and would like to discuss that. Most people are in the middle somewhere but deep down are one or the other, I believe.
When I'm at work, I can't stop talking.  When I'm in social setting outside work, I'm a wallflower.
Maybe your work interests you more, or you like your line of work.
I guess I would be a good subject for Wilhelm Wundt in experimental psychology
Hmm, never heard of him. What did he study?
He was a German physician and philosopher who is known to be one of founders of modern psychology.
Interesting. Freud is also popular bit I've heard most of his theories are now discredited.
