What is it...?

What is it
About your smile
That fuels me
For ten thousand mile

What is it
About your voice
That begs me
To scream and rejoice

What is it
About your looks
That cannot
Be explained in books

What is it
About your song
That makes me
Feel like nothing's wrong

What is it
About your laughter
That makes me
Sure of what I'm after

What is it
About your being
That shows me
That the world's worth seeing?!
