It was her smile that took me captive the day we met, and never once let me go. There was an authentic quality to her smile that made people stop and look; a basic human truth that seemed to emanate from deep within her and naturally find its way upward and out. Like the magma flow from Vesuvius, there was simply no stopping Cathy's smile. It could freeze people where they stood and hold them there, sometimes forever.That's what happened to me anyway.
