It must be odd to be 25 and know, relatively suddenly, more or less exactly what you will do (barring revolution or other nuisances) until, like your predecessors for a millennium or so, you breathe your last.
Whatever one thinks about the form of government of which it has turned out to be her lot to be the latest (and I, at least, doubt the last) figurehead, it would be hard to deny that she has done a bang-up job.
