(D, Am, C7M) 
I think I'm crazy 
because what I did 
but I am 
if I am not convenient 
I am here to be happy 
I am big and adolescent 
I think I'm going insane ... 

Refrão 2x: (A, C7M, D) 

I am a teenager 
I am happy and I like to do 
what I do 
rock and crazy 
I enjoy my friends 
doing the same bad for me 
because when I do bad 
they are still my friends 
Look around you 
Think the consequent 
because my heart 
often beats 

(C7M, D, Am) 
you changed me 
I like you moved 
when I met you 
my world was happy 
I am crazy 
crazy in love
