Verse 1:
    G              D
Oh, I had a lot to say

Was thinking on my time away
  G                                   D
I missed you and things weren't the same
                    Bm      Bm              G
'Cause everything inside it never comes out right
                   Bm     Bm             E
And when I see you cry it makes me wanna die

I'm sorry I'm bad, I'm sorry you're blue

This time I think I'm to blame

It's harder to get through the days
       G                         D
We get older and blame turns to shame
                    Bm      Bm              G
