I remember talking to Our Lady of Muswell school. It was in a library with lots of toddlers in it. They were wobbling about on their legs and dribbling over books and making fart noises with their mouths (the toddlers, not the children). But the pupils were amazing and listened brilliantly to me despite all the noise from the little kids behind them. They had a really nice teacher who helped them understand what an alchemist (it has the word chemist in it). Then they all wrote me letters and this was my favourite.
