Japanese usually expect to understand their own feeling.
I will provide some examples.
“I want you to leave me alone because I am exhausted.”
“I don’t require your help, because I can do it by myself.”
However I don’t to express my feelings. I want you to be sensitive and be able to notice someone’s emotions.
I’m sure, in Japan’s society that is possible. But, in other countries, it is impossible.
Foreign people don’t have mind reading skills like Japanaese.
Hence, I still have to express my feeling, opinions and my requests all the time.
It is a common way of thinking in the world.
