Ich weiß warum [English translation]

I know why

I am crazy

I know why

But I don't care

I know why

I can't think

When you are here

I can't think

And I carry on

(Na, na, ... )

If you say something

I cannot listen

If you say something

All I have to do is look at you

If you say something

Your words are flying

Like flowers through the room

And I don't understand anything

(Na, na, ... )
