Shenzhen: Powerless

Much scratching of heads this morning.  Arrived at work as a China Southern Power Grid van shot away.  No power!  In the end the message got through - no school!

The power did come back on at 9.30am (I had plenty of non-electricity based things to do to fill in the intervening two hours) which provided a valuable gift: no students and a good portion of the day to wrestle with end-of-year reports.
