Who Am I?

Who am I?
I'm a daughter
I'm a sister
I'm a twin
I'm a friend
I'm a writer
I'm a nerd
I'm an Asian
I'm a Christian
I'm a debater
I'm a lecturer
I'm a rock music fanatic
I'm a computer addict
I'm a flutist and I'm a violinist
And to some, I'm a monster
But knowing all this, even
You can't know who I am
And if you told me in these sorts of titles of whom you are
I wouldn't know who you were, either
I wouldn't know what that look on your face that you get when you remember
something funny
I wouldn't know what rushes through your mind rapidly
Or how you think
Or what can make you cry
And what can make you go solemn
And what you wish for
You just never can tell by some things
