The malodorous horrors of Sports Day. Bracing yourself for Parents' Evening. Refereeing teenage relationship dramas. This is not what you see in the adverts. From the age of eight, Ryan Wilson dreamt of being a teacher. This is the inside story of his time at the chalkface, from fresh-faced trainee with grand ideals to exhausted assistant head battling ever-changing government demands. It is a tribute to the colleagues who befriended him and to the chaotic, brilliant, maddening students who inspired and enraged him. From Sean, the wannabe gangster with a soft heart, to David, the king of innuendo, and terrifyingly clever Amelia. And, above all, it's about the lessons they taught him: how to be patient and resilient, how to live authentically and how to value every day.
