I'm a jerk 

but there are worse things to be

Sure, you can change your face and your waistline 

but there's not much I can do 

about my personality 

Yeah, I can watch what I say 

Sure, I can filter what you see

but my thoughts will always be mine

and as long as they're mine

jerkish is all they will be 

My parents were never cruel

my self confidence is perfectly fine 

don't you dare try to rationalize it 

the only thing wrong

is this personality of mine
