From a reader:

Apropos of nothing, my wife and I were standing on the corner of Lafayette Park during lunch today and an old woman was standing in front of us trying to hail a cab, to no avail. My wife said, “would you help her get a cab? I don’t think they can see her.” I replied, “why would you want to help Helen Thomas get a cab?” She stepped forward a few steps and whispered, “oh my god, it is Helen Thomas. Oh no, I wanted to help Helen Thomas!” My moral dilemma was averted when Helen managed to finally get her own cab.
