In "Wolf Hall," the narrator reflects on childhood fears of demons lurking under the bed. These fears, common in many childhood imaginations, evoke a sense of vulnerability and innocence. However, a comforting voice reassures the narrator, suggesting that demons are a distant problem, kept away by the guards on London Bridge, a symbol of safety and protection. This exchange highlights a contrast between childhood anxieties and the adult understanding of reality. The mention of physical boundaries, like the river and the guards, serves to illustrate how children seek reassurance and how their fears can be managed through parental guidance and community beliefs, creating a narrative that blends fantasy with the harsh truths of the adult world.
