F              Bb       F 
I know why you asked me here 
F                   C        F    
You're not sure the coast is clear 
F               Bb         F 
You're about to speak your mind 
F               C        F    
This small talk is a bad sign 

         C           Bb          F 
How many days have I been here tonight 
         C           Bb          F 
How many days have I been here tonight  
  
You keep stalling probably 
Stretch it to eternity 
Can't feel guilty say your lines 
Breakin' my hearts not a crime

Bb                C 
How long can I go on like this 
         C           Bb          F    
How many days have I been here tonight

Since I've been here tonight
