Define Teenage

I see nothing extraordinary
Nothing out of the ordinary
Schizophrenic dreamers and
Gene pool polluters

I don't know what you're trying to say
I don't care what you're trying to sell
I don't need anything from you
Or you or you or you or you

They tied hope to tomorrow
And didn't tell you that's when it ends
I don't know why you believe them
But you always seem to go along

I just want your little drug problem
I just want a little love problem
I see nothing extraordinary
I see nothing at all
