Greeting by headmistress on arrival for pick up at 3.30pm was "my, he has got a temper on him hasn't he?". Then had blow by blow account of the huge temper tantrum he threw when he got separated from his lunchbox and I left. It's hard to say which event tipped him over the edge, but for vanity's sake I'm going to say me leaving did it.
It apparently took every member of staff unsuccessfully trying to calm him down, before Mrs Head persuaded him to sit down on a chair (apparently sitting at the table was too difficult for him) to eat his lunch.
Once settled, he had a good time playing with the other kids and although his sharing skills were in short supply according to the teacher, he came home with a big smile on his face. He went outside to play 'What's the time Mr Wolf?' and depending on who he's talking to, he got to play Mr Wolf.
No need to ask if he had any letters for us, he came out and immediately handed me an envelope. All excited that it was some kind of school trip/drawing my darling had done, found it to be the invoice for this terms fees.
Final word. On way home in car after our celebratory smoothie in Farnham, Oliver announces he 'loved school' and had a 'lovely day'. Not all bad then.
