Who am I?

From V for Vendetta:

Evey: Who are you?
V: Who? Who is but the form following the function of what and what I am is a man in a mask.
Evey: Well I can see that.
V: Of course you can. I'm not questioning your powers of observation I'm merely remarking upon the paradox of asking a masked man who he is.
Evey: Oh.

I must admit, never had I presumed people "knew" me well enough to tell me what I am. And have the audacity to "cite" me as the source.

Don't presume too much.
