What is the most scary things that has ever happened to you?

The most scary thing in my life is when I was 16 years old. I had a chance to study in Japan for one year. It was my first time I had to stay away from my parents. In the first week everything was going fine, but the week after that there was an earthquake in my area, the very north of Japan. I had never ever experienced any earthquake in Thailand before. I remember at the time I thought it was the end of the world. What I thought at the time was about my family. I wouldn't have any chance to say goodbye to them, or even see their beautiful faces. I had been crying for an hour until my hostparents, who took care of me during that year, came to reassure me and explain to me that it wasn't harmful. But you know, even it's not scary for them, but it WAS for people who first experienced the earthquake Indeed, this scary thing will stuck in my memory forever and ever!
