It's been 18 years since September 11 attacks. Some people in their 20s may not know September 11 attacks. When I was watching TV, the TV screen suddenly switched and showed that the airplane crashed into the WTC. For a moment, I thought it was a movie scene, not a reality. But it was real.

I hope the incident as such will never happen again. I think what we can do for that is to understand each other and become friends. I believe that makes the world peace.
