Cool I am 
When I am with you 
Cool I'm not 
When I am lonely 

I feel so sad 
What I did wasn't right 
I feel so bad 
And I must say to you 

Sorry, but 

Nobody's perfect 
Nobody's perfect 
What did you expect 
I'm doing my best 

I feel so sad 
But you know I'll be [bad word] 
I feel so bad 
And I must say to you 

Sorry, but 

Nobody's perfect 
Nobody's perfect 
I was dishonest 
I will do my best 

Cool I am 
When I am with you 
Cool I'm not 
When I am lonely 

Perfect, perfect, perfect, perfect
