Well im not gonna post any, but this topic made me think- why havent the students of hogwarts made up Nicknames for each other and teachers? In most schools students are reffered to in nicknames... hmm
In Spanish class, I just learned that Quique is a nickname for Henry (in Spanish), and since Harry is a sort of diminutive of Henry, wouldn't Harry basically be Quique in Spanish? With that logic:
Harry= Quique Potter. What cool name would that be?
