Now my second story. Three years later, on a clear, bright, calm Sunday afternoon at Bondi Beach, also not far from where we now stood, from out of nowhere there came four freak waves, each up to twenty-five feet high. More than 200 people were carried out to sea in the undertow. Fortunately, fifty lifeguards were in attendance that day, and they managed to save all but six people. I am aware that we are talking about incidents that happened many years ago. I don't care. My point remains: the ocean is a treacherous place.
