So look, I've worked with teachers for the last two decades and more, and I want to acknowledge the tremendous passion that teachers have for what they do, and they have to have this passion because it's a really challenging job that teachers do. I admire enormously, even in a normal situation, the work that teachers have to get through, and over the last two years, my goodness, they have had to change and adapt. I'm not going to use that dreadful "pivot" word, but they really have had to change the way that they engage with their students, and they have worked incredibly, incredibly hard.
