As a kid I had the chicken pox 

the german measles and the scarlet fever 

and I don't ever want to go through that again 



I had to tell my little broken heart 

I had to tell it I'm immune to love 

'cause I don't ever want to go through that again

You can't have it once you've had it 

You can't have it once you've had it, no
