Hmm. Alright. My office door is open most of the time, you know, Serena.
Why can't any of these Ministry officials work out any problems for themselves? It's past midnight and I get yet another owl from them asking for 'Professors Dumbledore and McGonagall's assitance.' Bloody hell, they should pay me for this...
And if I demanded payment, one way or another I guarantee that my mother would find out, and then two days later I'd get a Howler from her furiously exclaiming at the gall I must have to ask for payment when I don't need the extra money. And then she'd go on and on about my lack of family, how i never visit, etc.
I'd rather skip all of that and simply do the work.
Oh, I'm sorry, professor. It must be hard to be a leader figure in such a hectic school. I now understand your problem with hormones. It's hard enough to deal with them while they're happening. However, dealing with them second hand, and on magic?
