MARYLAND HEIGHTS, MO–Despite attempts to conceal it from students, Eisenhower High School 11th-grade English teacher Matthew Geisinger was clearly hung over Monday. "Today, you're going to break up into groups of four to discuss that book you read over the weekend," Geisinger groggily told his first-period class. "The idea is to draw your own conclusions about the book without coming to me for any help." Geisinger then rested his head on his desk for the remainder of the period, occasionally taking a sip of coffee.
