I knew this word from my boss. I feel like that it is right.
Human relationship cannot take a shortcut.
We always need to behave kindly when we build mutual confidence. And We must not neglect a opportunity such as building mutual confidence.
I'm a freshman in my working. My office members are very kind and I respect them. I don't want to have become strained between me and them. So, I will always be trying to remember this word and to build it little by little.
