Unable to leave well enough alone.

We arrived home on Tuesday evening, after five hours in two trains, and the students were able to see the Queen on Wednesday afternoon. And no sooner do we all catch our breath and say goodbye to the first of those who will now steadily and swiftly depart, but we're off again, this time for one last group excursion to London. Next week, I suspect, I will sleep the sleep of the weary.
