who
I've come up with a good, I think, response for that question in the last couple of years; one without qualifiers, statements, or absolutes. I am me; no more, no less. I am who others think I am; sometimes more, sometimes less. Words can never fully realise or justify a person. Oftentimes they are limiters. A person must be experienced in order for you to know them; so although I can tell you lots of little details, none of it is really me - just as none of your details are you. We are who we are.
