I never can say goodbye, Michael ...

Everytime I think I've had enough, 
To start heading for the door. 
There's a very strange vibration, 
That pierces me right through the core. 
It says, "Turn around you fool, 
You know you love HIM more and more." 
Tell me why (tell me why), 
Is it so (is it so)? 
Don't want to let you go!
