My best friend all through childhood was a funny little girl
But overnight she became a woman of the world
I used to think of her as a sister throwing rocks and playing games
Now I don't know what to think of her everything has changed
Her life has become complicated living on the phone
Every guy wants to know her and won't leave her alone
Now she's telling me all about it messing up my fragile head
She wants to know who really loves her this is what I said
You'll never know if you don't know now
And I'm stuck between the in and the out door
You'll never know if you don't know now
And I don't think I should see you anymore
Sometimes I wish I had never caught her friendly glance
I could get on with my life, instead I'm learning to dance
She still thinks of me as a brother, that's a thought I'd love to erase
Maybe I will write her a letter, she's too much to face
You'll never know if you don't know now
And I'm stuck between the in and the out door
You'll never know if you don't know now
And I don't think I should see you anymore
Now she's telling me all about it, messing up my fragile head
She wants to know who really loves her, this is what I said
