To Make Magic

To your horror, the first thing you see when you open the trunk is someone else's knickers. You promptly shut the lid and latch it, wishing you hadn't dared to look. Unfortunately you were not quick enough, and an older girl passing by saw you snooping through what was obviously not your trunk. Apparently she knows the girl whom the trunk belongs to, because within minutes the two are yelling in your face about right and wrong and how you are a rude little kid with no sense of personal boundaries. The owner of the trunk boxes your ears as she leaves, and they ring all the way to Hogsmead Station.
