I have a few words in defense of my youth My regrets will fill an ocean or two I was young I didn't know What I would stumble into I had a lot on my mind And there were so many rules It makes a girl crazy Makes you break a few And there I go again Acting like it's my fault When you're to blame It makes me happy To use you a little Just to use you a little To write this song It's the very last letter To an old lover To say I'm glad you're gone I've got snapshots of things in my mind Though I left the past We don't leave it behind But I learned And now I know That I don't need you comin' around One thing I should probably say, I got over it all and I surrendered the pain That's the thing about mistakes You never see 'em comin' Till it's too late It makes me happy To use you a little Just to use you a little To write this song It's the very last letter To an old lover To say I'm glad Sacrifice my happiness It's not enough to know I'm better off the way it is Makes me happy To use you a little Just to use you a little To write this song It's the very last letter To an old lover To say I'm glad It makes me happy To use you a little Just to use you a little To write this song It's the very last letter To an old lover To say I'm glad you're gone
