I know why you asked me here 
F5                   C5        F5    
You're not sure the coast is clear 
F5               Bb5         F5 
You're about to speak your mind 
F5               C5        F5    
This small talk is a bad sign 


         C5           Bb5          F5 
How many days have I been here tonight 
         C5           Bb5          F5 
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

How long can I go on like this 
         C5           Bb5          F5    
How many days have I been here tonight
