Important? I think Not.

Can someone please tell me why I need to know Astronomy? I don't care if the stars look like anything or not .I can find the big dipper and thats about it. Why does it matter what degree the angle is between me & the north star? Someone please tell me why I am enrolled in such a pointless class. Please...cuz its 12:44am, I have an assignment due and a test to study for. Neither of which I have bothered to do yet.
