’March 11' and ’September 11' and .......

Today is September 11, 2018. In Japan, it is said that 7 years and a half passed since March, 11 of the Big Tsunami Earthquake of East Japan.
In the United States, it is said that 17 years had passed since the September 11 terrorism.
7 and 17, both have the number 7.
The two events, both dramatically changed people's lives and minds, thoughts etc.
One is a natural disaster and another is a terrorism, but both deprived people of happy lives at once.
This morning, at high school, before starting my International Relations (IR) class, I asked my students to pay one minute of silence together.
A silence is an expression, a silence is a universal language. Anyone can share the time and the space together with others under a silence. It creates a harmony and a peace.
We did not talk, but we understood and we prayed for the victims in the world.
