I can be very introvert when my brain is preoccupied by something interesting, but when I am with other people I an usually quite extrovert. I tend to be courteous and attentive to persons that I am with on a one-to-one basis. You for example.
I am a devotee of classical music, listen to it as much as possible, I love concerts, all from Shostakovitj's weird string quartets to Beethoven's symphonies. And I love Opera.
I do eat, but also cook (decently). Anything is fine with me as long as it is tasty.
Or I may be looming over some piece of computer code that bugs me. And if you don't watch out, I'll tell you about it!
