Walking on that beach this very morning, she noticed the tide had gone out and that the water was frothy like a pint of beer. It remembered her the newsreel film her geography teacher had shown her two weeks earlier. She was convinced that a tsunami — a word that nobody hadn’t even heard before — was happening right now. She tried to explain and convince her parents so hard that they told the security guards, lifeguards who cleared the beach. By the end of the day, everyone in the world knew what a tsunami was. Because that tsunami killed a quarter of a million people on beaches in 13 different countries. But there was one beach where no one died. Mai Khao Beach, Thailand.
