Well, he's there! And I didn't cry! Felt oddly excited this morning, because he was, and concentrating too much on going in the right door, etc, when we arrived to be sad. His little face fell though once he realised we were going, and he was being left in this strange place, and I did start to lose it. But we had to do boring stuff like pay for snacks, buy the book bag, etc, so I had to hold it together. By the time I'd left the building, the crying moment had passed.
Might not be the case tomorrow, however!
I must get some black ankle boots to replace the pleather ones I got from Tesco last year. Only £18, and I wore them to death. Sweaty though.
