Sooo...

It is advisable that you leave this post immediately, as I will go totally nuts.
I got my school books today.
All but three.
OH MY GIDDY AUNT, THEY'RE SO HEAVY!!!!!! Your backpack should only weigh 10-15% of your body weight.
Those books are WAAAAAY more then that. I'm going to be a freaking hunchback by the time I leave school!!! We needed three large carrier bags to fit the books in.
AND I HAVE TO CARRY THEM AROUND ON MY BACK?!
AAAAAARRRRRRGGGGGGGHHHHHHH!!!!!!!!!!!!
