Although Dahmer claimed to have “had normal friendships in high school” and “a good social life”, a member of his social group, John Backderf, said that he was merely amused by Dahmer’s propensity for bizarre pranks and jokes and had no desire to forge a close friendship with him. Backderf characterized Dahmer as “creepy” and made it a point to avoid socializing with him outside of school. Classmate Mike Kukral was similarly amused by Dahmer, but also failed to get close to him. “No one really knew what was going on in his mind,” Kukral said. “He didn’t open up to anybody.” A cashier at the Eastview Junior High School cafeteria recalled that Dahmer joined others at the tables to eat, but always left the cafeteria alone. Dahmer’s difficult personality and inability to trust others left him friendless by the end of high school. “I really hadn’t any close friendships after that, after high school. I just sort of lived in my own thought life, fantasy world,” Dahmer said in a 1993 interview.
