The actual teaching of planned lessons, just me, on my lonesome, who'da thunk it?  Maths first thing and science following afternoon break. And after all that, The Weekly Meeting with tea and, erm, more planning for more lessons to come...

2) It was the first one I fished out the dishwasher in the staff room

Direction?
