       D 
Dear today, tomorrow here 
                  G                          D 
Man I was just checkin' in, hope you’ve been well 
  
Me, I'm doin' alright, could always be better 
           G                   A                   D 
Seein' as you're the only one with a choice in the matter 
  
If I know you, hell, you're too busy 
                G                        D 
To do damn near anything, that you ought to 
                   D 
I guess what I'm sayin' is, if you don't change 
                 G               A            D 
Boy, you'll be kickin' yourself one of these days
[Estribillo]
          G 
So maybe you should call our Mama, have a drink with our old man 
       D 
Quit wastin' our sweet time and put that diamond on her hand 
     G 
Stop takin' me for granted like I'll always be around 
       D 
Cause even as you read this boy that clock is tickin' down 
A                            G 
And remember every second I got's borrowed 
                            A                D 
So I hope you think of me today, sincerely tomorrow
[Estrofa]
                 D 
Listen I ain't tryin', to bring you down 
                    G                         D 
Cause I sure know better than, pushin' you around 
                     D 
I guess I was just lookin' out, for you and me both 
      G               A         D 
Cause we both lose if I told you so
[Estribillo]
          G 
So maybe you should call our Mama, have a drink with our old man 
       D 
Quit wastin' our sweet time and put that diamond on her hand 
     G 
Stop takin' me for granted like I'll always be around 
       D 
Cause even as you read this boy that clock is tickin' down 
A                            G 
And remember every second I got's borrowed 
                            A                D 
So I hope you think of me today, sincerely tomorrow
