Get rid of all backpacks and hand bags. Every boy and girl carried their books, paper, pen etc. in their hands to school when I went to high school plus colleges.
What country and what year was that? Even in the early 1970s we took bookbags to school.
My kids have lockers but rarely use them. They would rather lug a 400lbs backpack around all day, utter insanity. When I was in high school I would get maybe books for two classes and a notebook and pen and then go to my locker for the next two classes. If I had homework I carried only those books home.
In college I kept my books in my back car seat and had a brief case I carried with again books for two classes and a notebook and pen. I don’t get the kids and their backbreaking backpacks.
