Say Goodbye

I don't know what happened
You were fine and so was I.
But you did not come today
And never looked again.

I hate you, but I do not know why.
But one day you will come
And I will not help you.

Hey! Look at me
And tell me what happened.
Hey! Tell me
What goes on in your head
Hey! Tell me
What goes on in your head
Hey! Say goodbye.
