"You don't know me", you told me once

You're probably right—I don't
I only know this;
You love to play your mind game
Cause I will keep on losing
You have a nicotine kiss
Cause I quit smoking for yours
You left then you come back
Cause you cannot deny me
You speak softly
Cause you always pull me close
You look beautiful asleep
Cause I'm attached to your sighs
You listen
Cause you keep things to yourself
You barely let me in
Cause you might change me

And you fond of me
Like I do you
