Describe a book you read that made you happy

I'd like to talk about a novel by Nguyen Nhat Anh, whose title in English is Ticket to Childhood. It's a slim book, and probably one of the best-loved Vietnamese stories of recent years. I read it in my second year at university in Hue, at a time when I badly needed cheering up. It was the rainy season, it had been pouring for about ten days, and I had just failed a statistics mid-term. My older sister posted me her copy with a note inside that said, "Read this before you decide your life is over." So I did, in two evenings, under a blanket. The story is told by a middle-aged man looking back on the year he was eight. He and his three friends decide that life is boring because every day is the same: wake up, school, homework, bed. So they start breaking the pattern in small ways, for instance by inventing new names for ordinary things, so that the adults can't follow a word they say. Not much happens in terms of plot. It's really a string of little episodes about how children see the world, and how baffling grown-ups look from down there. It made me happy for two reasons. First, it's very funny; I laughed out loud so often that my roommate asked to borrow it before I had even finished. Second, it took the pressure off. I recognised my eight-year-old self on almost every page, a kid who thought a bad mark was the end of the world on Monday and had forgotten it by Wednesday. That put my failed exam in perspective. It never fails to lift my mood.
