My mom harassed the school into giving me two sets - one for home and one to hang out in the classroom. Man did that make my life easier. It could have been quite a bit easier if I hadn't had a locker on, oh, the second floor.. far away from any of my classes... when I didn't actually have a class on the second floor.
It makes me wonder if the people handing out locker assignments are malicious, too fed up with sorting out schedules to give a ****, or just *that* stupid with the number of kids I know who can't even use their lockers because they're so far out of the way and there are only a few minutes between classes.. and if you're late for lunch you end up waiting in lines long enough that when you finally get your food you end up eating it in class instead of the cafeteria because the bell has already rung. There's just no time to go to your locker, and so then most of us end up carrying 40lbs of books around all day. And it's not like you can just leave your backpack in class or something... because then everything you own gets stolen.
