Nice conference

Spent a couple of days away at a conference: I was the first plenary speaker, and naturally I stayed around for the rest of the meeting.  I really enjoyed lots of talks --- mainly by undergraduates about research they had done, and felt good about encouraging them, and pointing them to new potential directions to examine.
I've received some wonderful mentoring in the past, from several directions, and it always makes me happy to be able to pay back some of this by passing the advice on forward.

Yours, suddenly realizing that I'm a "senior" mathematician, not a "junior" one any more.
