A couple of years ago, I got out of my car after a long work day and was greeted by an old lady. She demanded to know if I were a "cop." I told her no and asked if she needed a cop. She said yes. . . that her daughter was abusing her. So, I called the police and then the next day, like a good citizen, called adult protective services.
Tonight, in a social setting, I met a woman who claimed that my name was familiar to her. We went back and forth a bit on the possible connections . . . and she said that she had been the social worker who had taken the report from me a couple years ago. I was gobsmacked over her memory. That was pretty impressive.
I think we may need to recruit her for the army.
