I can't speak English.
I can't speak even in Japanese well.
Why can't I speak?
I know the reason why I can't speak, because I don't trust
Written language carries responsibility, because it affordｓ proof.
On the other hand, spoken language is irresponsible, and
people can easily tell a lie.
I dislike speaking fluently and don't like the persons who
are good at whitewash.
I want to believe the potential of written language.
