Father and Son Sudoku session

Took this hastily after arriving late home after parents evening.

Had a walk-through from the principal today, I don't know what he thought, but I think it was OK. And some students bought me a present of a stamp which says "super" with an octopus! They proudly presented it as the principal arrived, I think they thought he would be impressed, bless them.

Day off tomorrow, thank goodness, time for me to do lots more planning.
