Last Letter lyrics

I have a few words in defense of my youth
My regrets would fill an ocean or two
I was young, I didn't know what I would stumble into
I've had a lot on my mind and there were so many rules
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
[ Lyrics from: http://www.lyricsmode.com/lyrics/k/katharine_mcphee/last_letter.html ]
I've got snapshots of things on my mind
Though I left the past we don't leave it behind
But I learned and now I know
And I don't need you coming around
One thing I should probably say
I got over it all, and I surrendered the pain

And that's the thing about mistakes
You never see them coming
Until 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
I'm smart enough to know
I'm better off the way it is

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
