I decided not to be a giant idiotic wuss and went to the close one, and as far as I know, she was not there. Seeing as how she has lived in the neighborhood that she is still in for over 10 years (and probably a lot more) and I am frequently there because the university where I teach is in that area and I have many friends that live in that neighborhood and it is a hot spot for restaurants etc and I have never run into her or even seen her out - it was absolutely not a legitimate concern.
