It's nothing compared to the Fidelius work, or the camps or a dozen other things, and I know that.

I don't know what I'd do if I couldn't teach.

Getting to teach someone as gifted and passionate about it as Evelyn is - well, the thing that keeps getting me out of bed some mornings. Just, I know most people think astronomy's useless, or at least useless to most people.

I am working on something that might give us a direction about the first wards, or maybe the portkey problem. Maybe. Be a few weeks at least before I can even say if it'd help.
