Intense, serious but great sense of humor, playful and good at practical jokes / slapstick / straight man ploys.

Observant, intelligent, witty and quiet.

When people feel I am being an introvert, and working too much, they make comments like "should get out more" and "meet some people" and "just do stuff".

When people feel I am being an extrovert, they make comments like "doesnt he ever stop partying?" and "is everything about the meet n greet with him or what?" and "he needs to get serious, sit down and get some work done" and "what is he doing with his life, just meeting people all the time, heh"

Women sometimes one-glance me and move on, at a party or social setting. Then they see who I am with, when she is back from circulating or whatever, and they double take. The wheels turn. Behind their eyes the question burns "What is it with him that _she_ is with him?"... too late, chance to chat has passed, sometimes its best to gut check rather than bling check, smiles.
