ABSOLUTLEY NO OREOS!
Perhaps only the librarians can account for what took place and why Oreos are the only product on the banned list. Experts cannot give a definitive answer (because experts don’t really care), but we’re curious. Libraries and snacks usually don’t go hand and hand, but just Oreos? Why not digestive biscuits?
Perhaps there was a food fight that involved the best cookie in the world, or maybe someone was eating Oreos without a glass of milk. Whatever took place on that fateful day will be forever lost in the unwritten archives of this library with randomly specific laws.
