Bill was a voracious reader as a child, spending many hours pouring over reference books such as the encyclopedia. Around the age of 11 or 12, Bill's parents began to have concerns about his behavior. He was doing well in school, but he seemed bored and withdrawn at times. His parents worried he might become a loner. Though they were strong believers in public education, when Bill turned 13, they enrolled him at Seattle's Lakeside School, an exclusive preparatory school. He blossomed in nearly all his subjects, excelling in math and science, but also doing very well in drama and English.
