TIP: Campus theft can be tragic.
If you are a college student, your backpack will no doubt contain "your life"--irreplaceable notes, schedules, handouts, and work besides valuable books. Don't ever leave your backpack out in the open when going into the college bookstore or outside the cafeteria when going in to eat. Keep it with you or lock it up in a locker. Don't leave your materials out in the library while going to the bathroom or another place in the library. A stolen backpack can devastate your semester.
