It is a very long time and not remotely long enough. I still find even now that I am learning new things. I think it's you students that keep me learning. I see the world through new eyes every year. I'm looking forward to seeing how you'll do, Alice.

[A pause and a smile, warm and inviting.] Really now? Well, I hold quite a few classes every year, for all manner of skill levels. I will be glad to have an eager learner. And if not, I always hold office hours for those that want more practice or time within their own research.
