While Hermione wished her parents were around more, she really did love her nanny, Julia. She had cute glasses with purple rims, dark skin, lovely fluffy curly black hair even frizzier than Hermione’s curly brown locks, and – most exciting of all – she was studying maths at university, which sounded much less icky than being a dentist. After school, Julia would walk Hermione home and make her snacks. She practiced times tables with her and gave her tricky maths puzzles to solve – like how to get a bunch of animals that would fight with each other across a river in a boat with limited capacity, and how to cut a cake into eight equal pieces with only three straight cuts. She clapped when Hermione’s violin practice went well, and sang to her when she was sick. And then one day, she solemnly announced that she was leaving.
