Lyrics:

I received my invitation to your party
And I hope that you don't think that I'll attend
Although I'm not conceited or a smarty
I still recall the things that might have been
I recall the many times you said you loved me
(Said you loved me)
Before your someone new drove us apart
(Drove us apart)
Did you invite me to your party
'Cause you miss me?
(You miss me)
Or to let your friends all see my broken heart

So, you see why I won't be there at your party
(At your party)
I see you, and my heart would break but you
(Would break but you)
So, I'll just keep my kiss-stained invitation
(Invitation)
You go ahead and keep your someone new
