When the tsunami struck in, people who were able to escape watching their own homes being destroyed. Water flow in so quickly and strong, just within a second, the wave engulfed the whole town. At first, they can’t believe what have they seen and what had happen to their house, and the minute later, they forget their worries of their loss of properties, they started shouting “Faster, faster” to a group of people who were on their way to escape the wave. The wave came so fast, some couldn’t escape. Aftermath of tsunami, the whole world was impressed with the calmness and unity of Japanese. But behind these calmness, they’re in dismay of losing many, even to see people to be engulfed by the tsunami in just a few feet distance from them. No one would understand what’s their feeling. What else we can do? Only God knows. All we need is more pray, pray for forgiveness for the people out there.
