(Intro)

C - F
C - C/B - C/G - F x2

(Verse 1)
C                        F
I set all my regrets on fire
          G                        C
Cause I know I'll never take the time
C                           F                        
To unpack my missteps and call all of our friends
     G                          C
I figure they would take your side
                              
(Pre Chorus)
            F                  C
I make the bed, just not that well 
                 F      
Your name comes up a lot
         F    
When I talk to my mom
         G
Oh, I think she can tell

(CHORUS)
        C
I was out on the town
      C/B          C/G     F                        
So I came to your window last night
          C                         
I tried not to throw stones
        C/B      C/G    F
But I wanted to come inside
           C                       C/B         C/G      F
Now I'm causing a scene, thinking you need a reason to smile
   Am    G           F
Oh no, what have I done?
          F                 C
There's no one to keep me warm
 

C - C/B - C/G - F


(Verse 2)

      C                      F
So maybe I should put up a fight
                 G                     C
I'll call them back and borrow a box knife
    C                         F                             G           C
So I can learn to live with all the stupid s*** I've been doing since '99
       
       C                     F
And I know I could be more clever
        G                     C/B
And I know I could be more strong
         C                       F                        
But I'm waiting for the day you come back and say
        G                        C
"Hey, maybe I should change my mind"

    F
I drink a lot
          F             C
I'm not sure if that's new
            F                          F   F   F
But these days when I wake up from a night I forgot
         G
I just wish that it never came true

(CHORUS)x2
        C
I was out on the town
      C/B          C/G     F

          C                         
I tried not to throw stones
        C/B      C/G    F
But I wanted to come inside
           C                       C/B         C/G      F

   Am    G           F
Oh no, what have I done?
          F                 C
There's no one to keep me warm
 
(C-part) 

        C                    F
And I know I could be more clever
        G                    
And I know I could be more strong
        C                     F
And I know I could be more clever
        G                     
And I know I could be more clever

                           C                           C/B
I knew there would come a day when all was said and done
(And I know I could be more clever)
              F                      G
Everything I was is everything but gone
(And I know I could be more strong)
               C                           C/B        
All my big mistakes are bouncing off your wall
(And I know I could be more clever)
                     F                       G
The bottles never break, the sorrow never comes
(And I know I could be more clever)
                   C                 C/B
So come on let me in, I will be the sun
(And I know I could be more clever)
                 F              G
I will wake you up, I am who I was
(And I know I could be more strong)
                   C                   C/B                 F
Just open up your heart, open up your heart, open up your heart
(And I know I could be more clever                          
And I know I could be more)

C - C/B

(Chorus)

        C

   Am    G           F

          F                 C
There's no one to keep me warm
