One of Us: The Story of Anders Breivik and the Massacre in Norway by Ǻsne Seierstad:
Anders had been exempted from military service because he was registered as his mother’s carer. After a serious herpes infection she had had a drain inserted in her head and she needed nursing for an extended period.
Lene was touched by the care Anders gave his mother. He told her how his mother was faring after her illness. She had changed since the surgical procedure, he said, become more absent-minded, more disorganized and terribly depressed.
Anders had also told Lene about his mother’s unhappy childhood, about his grandmother who went mad and the uncles his mother never wanted him to meet. He told her how self-sacrificing his mother had been when he was growing up, on her own with her two children. But he also criticized her for having lost touch with her relations. He would so much have liked a big family.
