who are you ?

If I was a real graffiti artist, I would probably be the type to create art pieces that get people to look inwards or inspire them. Very often when I meet new people, I automatically asking "what do you do?". I guess it's the standard question we've been programmed to ask.  But what I really want to ask is "who are you?".  Strangely it's often a difficult question to answer and many don't seem to have an answer it either ... how strange is that?
