Having fallen in love with Gardiner at the same time as I did with Diane Ravitch, but whilst so busy with too many other things, I never had pause to wonder where he might have ended up placing phronesis on his scale.

Almost forty years down the road (women zai shuo ba) but never too late. What a wondrous grandmother you should be...
