Mistake

I made a mistake, and I'm sorry
I was wrong, and it's hardly enough just to say the words
I misled, I regret it, and she won't forget it
I'm just a fool, I'll admit that I am

Who's laughing now? I heard she found
Somebody new to give her heart to
I wore a crown, I'm trading it in for a permanent frown
'Cause my baby ain't my baby no more
