Who am i?

A friend told me the other day that i am unique. According to her i don't care what the world or the society thinks about me.. i just do my thing.. and when i get involved in something i give it my all. and even though i hardly have any friends and i am lonely but i am comfortable with my loneliness.. i don't let it get to me. That's usually where most people fail but i carry it just fine.  

Almost all of it is true. But what amazes me is even though almost every other person is able to tell WHAT i am .. none has ever been able to tell WHO i am. And that is the biggest tragedy in my life.
