Does NO ONE listen to prefects anymore?

I have not been around the common room the last few evenings as I've been busy in the library working on my project for Ancient Runes. To my intense annoyance I discovered this morning that Fred and George ignored what I told them on Monday and brought that dog, that unauthorized MONGREL, into the common room. No doubt it has been infesting the furniture with fleas.

As soon as I talk with Professor Macnair, that dog will be OUT. Unfortunately, however, I've had difficulty locating him (Professor Macnair, I mean, not the dog, who has been painfully evident). The Professor has not been keeping his usual office hours this week, so I didn't find him this afternoon, although he's been there, of course, in lessons and at meals.

There is too little attention paid to keeping the rules around here sometimes, I think.
