I'm afraid that Sir Nicholas's special day has been thoroughly upstaged. I understand that he's quite beside himself at the moment. Professor Lockhart was in here this afternoon with one of his first years who'd got frostbite while sitting in their common room. Apparently Nick's up the tower, freezing them all out of the dormitories.

I feel certain that by tomorrow, Professor Lockhart will have a new heroic exploit to boast of.
