Dahl attends Llandaff Cathedral School, a religious school for boys that is located about a mile from the family home, for two years between the ages of seven and nine. One of his two memories from this time is seeing a boy a few years older than him speeding down a hill on his bicycle with his arms folded “casually across his chest” (24).
