I can't speak!

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 spoken lauguage.

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.
