Describe William's first experience with magic. What did he learn from this experience?

As a child, William first encountered magic in the form of a supposed curse by a witch doctor. After being given candy that was, unbeknownst to him, taken from an angry trader who vowed to curse those that ate the candy, William, stricken with fear, confessed all to his father. Subsequently, his father spent a large sum of money to simply buy the bag, comforting his son to no small degree. His father approached all magic with the same air, confronting the problem at its root and taking a no-nonsense approach to it.
