I think if NCpbm didn't really know the neighbor or their personality, then yes, she is over reacting, because it could have been anything that others have mentioned, but when you know the person, and you know how they do certain things, and often do it just to "push buttons", then you get a bit angry over it.
Yet another reason why I would LOVE to live out in the middle of nowhere.
