A Really Good Question

Why is it that all of your teachers give you a ton of homework on the most inconvinient night? For example, tonight, I had homework in algebra II, spanish III, ap euro (which I have a test in on monday), and ap bio (whicih I have a test in tomorrow!) When I got home from school, I spent (litterally) 4.5 hours doing homework...non-stop (that ain't right). Now I'm tired, and I have to find some source of energy to get up for zero hour tomorrow, it's probably going to be "one of those days"...( ya know, look like crap, feel like crap, can't focus...)...and to make my life even better...I have to be on camera tomorrow for advanced public speaking (I just had to be host next week! Didn't I!)...life sucks don' it?.......grrrrrrrrrrrrrrrr!
