The world is a dangerous place – at least according to Christopher Boone, who sees danger in anything and everything that's unfamiliar to him. Most of the time he's okay since he makes sure to stay within his comfort zone. But, halfway through The Curious Incident of the Dog in the Night-Time, circumstances force him to bravely thrust himself outside that bubble, and the world he finds outside is a scary place indeed. Why is it so scary? One could argue that it has a lot to do with the degree to which Christopher is able to control every aspect of his daily life, and predict every event sneaking up around the corner. When that tight control is taken away, he's absolutely paralyzed by fear. And we all know that "tight control" is simply impossible to achieve all the time.
