The reason

Boy: Do I ever cross your mind

girl: No

boy: Do you like me?

girl: Not really

boy: Do you want me?

girl: No

boy: Would you cry if I left?

girl: No

boy: Would you live for me?

girl: No

boy: Would you do anything for me?

girl: No

boy: Choose--me or your life

girl: my life

 
The boy walks away in shock and pain and the girl runs after him and says...

The reason you never cross my mind is because you're always on my mind.

The reason why I don't like you is because I love you.

The reason I don't want you is because I need you.

The reason I wouldn't cry if you left is because I would die if you left.

The reason I wouldn't live for you is because I would die for you.

The reason why I'm not willing to do you anything for you is because I would do everything for you.

And the reason why i would choose my life is because you are my life .
