This time, words of a bulletin board is
”Ryoukan's one-liner precept"
Too many wodrs
Too quick to speak ?
Speak noisily
Say something that hasn't been asked
butt in on one's conversation
Talk back
Speak before the other person has finished saying what they want to say.
By the way, I was given a pamphlet like this some time ago.
I reflect on myself and feel ashamed.
