Intro:

C Am G
C Am G
F


Verse 1:

           C            Am     G
Well I got everything I need
                      C
In the backseat of my car
   Am          G
Got plenty of sweaters
            C
I got those CD's that you like
             Am
And all the songs we sang last night
          C    Am G
And I got you

     C             Am    G
And sometimes you frown
                            C
And sometimes you look scared
     Am       G
Well, I am too
                C               Am
I'm scared that no one will be there
                 G
I'm scared that no one really cares
            C        Am G
When it gets rough


Chorus:

F            G
I'd love for you to stay
               C
But how do you feel
               Am
Now how do you feel
F             G
I'd love for you to say
              C
Just how you feel
             Am
Just how you feel, instead of walking away
F        G
Just say anything
    C                      Am
Anything would be fine, anything would be fine
F             G (single strum) C Am G
I'd love for you to say anything


Verse 2:

C Am G
               C                 Am    G
And now we're right back at the start
                  C     Am
Where it started before
             G
Where it began
               C            Am
With all those awkward silences
               G
And all those awkward moments
                 C            Am         G
That I wish would never, ever, ever, ever pass


Chorus:

F            G
I'd love for you to stay
               C
But how do you feel
               Am
Now how do you feel
F             G
I'd love for you to say
              C
Just how you feel
             Am
Just how you feel, before you walk away
F        G
Just say anything
    C                      Am
Anything would be fine, anything would be fine
F                    G                C Am G
'Cause I'd love for you to say anything


Whatever this is:

              F
And she said:
              G
How do you do
            C                
How do you do, do, do this
           Am
How do you do, do, do this
              F
How do you do
              G
How do you do
            C
How do you do, do, do this
           Am
How do you do, do, do this
              F
How do you do
              G
How do you do
            C
How do you do, do, do this
           Am
How do you do, do, do this
              F
How do you do
                G
And why do you do
            C
Do this to me?
