Their boys were young, and curious about everything—there were a million and one other subjects to explore with them. Mark, who spent all night listening to people rat on their neighbors, didn’t want to raise paranoid isolationists, and Starr refused to have them worry. “We worry about them,” he told Mark with some regularity. “They don’t need to worry about me. About either one of us. About anything—it’s not their job.” He drove them and their friends in the police car to do things like get ice cream and go sledding and basically created the impression that he spent his days rescuing kittens and helping old ladies across the street. Obviously they knew their Pops was a police officer, but Mark and Starr made every effort to emphasize that it was just a job. Some people’s parents were doctors and nurses, others were mailmen and bus drivers, Starr was a cop. A guy had to do something; he played with sirens.
