[Chorus]
G
You know something I don't
Gsus2
It's not like you to be cold
Em/D                  C
Every night replayed over and over
G
You say things that I don't
Gsus2
You make me feel alone
Em/D                 C
Every night replayed over and over


C
You say it's no concern
                     G      
And everything's alright
C
Sometimes we all get burnt
                      G      
And then we try to hide
C
And I know, and I know, and I know
                
And I know we're wrong
                             G      
We should have let things slide

[Bridge]
G
And when the night gets dark
Gsus2
And there's no way back
Em/D
I'll call your name
C
But it's fading, we're fading

[Chorus]
G
You know something I don't
Gsus2
It's not like you to be cold
Em/D                  C
Every night replayed over and over
G
You say things that I don't
Gsus2
You make me feel alone
Em/D                 C
Every night replayed over and over


C
So many times you say
                        G      
You're staying out tonight

[Michael solo]

I wish that I could just walk away
                          G     
But I won't leave you behind
