The thing about used books at my school was that the school bookstores wouldn't buy them back a second time, even if they were in perfect shape. Fucking sucked.
When I was at school (which in Australia refers to up to year 12) I always hated seeing the ads on TV during the last week of holidays which advertised stationery and crap with the phrase "Back to school!".
The last thing I wanted was to be reminded that holidays are nearly over. 
Oh yeah, I hated that, especially in elementary and junior high school. Even now having graduated university almost four years ago, I still get this weird feeling whenever the summer is ending and fall starts up; it's been burned into my brain I guess.
