I think the least believable part of the Harry Potter novels is the idea that all these feathery quills and pet cats are getting along in perfect harmony. Let me tell you, J.K. Rowling, not a thing would get done at Hogwarts!
From personal experience of pencils, ballpoints, erasers and anything else which can be pinched from or knocked off a desk, then played with until it can’t be reached any more, the first spells learned must have been for Detection Of Things Hidden Behind Furniture, or the Levitation of Sofas And Chairs To See What’s Under Them.
I’ll leave the bad Latin versions of those for someone else.
