At first I didn't understand when she walked through the door 
You let go of my hand and then I knew there must be more 
I tried to tell myself that you were only friends 
But your eyes betrayed the smile you gave 
And I knew right there and then 

You were changing faces 
Right before my eyes 
One for her and one for me 
And then I realized 
Changing faces 
That moment I was sure 
I'd be changing places with her 

Please don't introduce me, don't be so polite 
Tomorrow I'll get over you if I just get through tonight 
I don't think I can stand it while she's standing over there 
If you just want someone on your arm 
Then she's the one to wear 

You were changing faces 
Right before my eyes 
One for her and one for me 
And then I realized 
Changing faces 
That moment I was sure 
I'd be changing places with her 

I think I'm gonna walk away 
Head right for the door 
Maybe I should stay and fight 
But look what I'd be fighting for 
I wanted so much more 

Changing faces 
That moment I was sure 
While you were changing faces 
I'd be changing places with her 

Changing faces 
The look that did you in
One for her and one for me 
Now I can't go back again 

Changing faces 
That moment I was sure 
I'd be changing places with her 

Right before my eyes 
One for her and one for me 
Neither one I recognized 

Changing faces 
That moment I was sure 
I'd be changing places with her
