The teacher sat with her handbag clenched in her fingers, ready in case she needed to leave suddenly. Her eyes seemed to dart from window to door, checking her exits. At first, she wasn’t even willing to tell me her name, and, for her protection, I won’t repeat it here. She is a teacher in the English-speaking region of Cameroon, a country where most of the population speaks French. When she told me about her students, she loosened her tight grip on her handbag, and her eyes locked solidly on mine.
