[Verse 1]
I have a few words in defense of my youth
My guts are feeling 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

[Pre-Chorus 1]
And there I go again
Acting like it's my fault
When you're to blame

[Chorus]
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

[Verse 2]
I've got snapshots of things on my mind
Though I love the past, we don't leave it behind
But I learned and now I know
And I don’t need you comin' around
One thing I should probably say
I got over it all, and I surrendered the pain
[Pre-Chorus 2]
That's the thing about mistakes
You never see 'em comin'
'Til it's too late

[Chorus]
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

[Bridge]
Sacrifice my happiness
It's not enough to know
I'm better off the way it is

[Chorus]
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
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
