《day after tomorrow》的詞曲創作由艾薇兒·拉維尼完成，其歌詞如下：
Verse 1：
Day after tomorrow, I'll be gone for good
Without you here, I'll be alright
I'll find someone who cares for me
And I'll be strong, I'll be strong
Chorus：
And I don't feel sorry for you
Cause I know you'll do the same to someone else
I'm not the one for you
And you're not the one for me
Verse 2：
Day after tomorrow, we're through forever
You'll find someone who loves you more
And I hope they love you more than I did before
And I'm sorry, but that's the way it is
Chorus：
Bridge：
It doesn't matter how hard I try
There's no denying what we felt was right
I just can't let go, even though I know you're not the one for me
Chorus：
Outro：
So here we are, forever changed forever goodbye forever goodbye.
