Don't you EVER do that again. My belongings are not your belongings, even if they happen to be sitting out in a box in the common room. What if you had dropped plum tart on the fabric, or stepped on the train? What if...? I'll tell you what if: all your hair would be cut off and flushed down the loo, that's what!

I suppose I'll just have to start putting protective charms on my clothing and jewelry to keep you from trying it on and swanning about like a Princess. Very nasty protective charms.
