Jill says the first time she realized that her memory was better than most people's was when she was 12.
"I was sitting and studying for a science final, and my mom was reading my science work. I started thinking about the year before, when I was in sixth grade, and how great sixth grade was—because I was now at the end of seventh grade and doing finals and I was under a lot of stress," she says. "I was thinking about the year before and how I was on a field trip on this day and I was doing this on this day and then it dawned on me: Oh my God, I just remembered a year ago today."
Jill says she even asked around to see if other people had similar experiences. "Two months later, I was with a friend of mine on the beach and I said, 'Do you realize a year ago today we did the same exact thing?' And she looked at me and said no," Jill says. "That was the first time I ever said anything to anybody about it—on July 1."
