プレゼンで無理に意見を言うより、下手な考え休むに似たりだと思う。
I think it's better to remain silent than to force an opinion in a presentation and risk sounding foolish.
彼の提案は場違いで、まさに下手な考え休むに似たりだった。
His proposal was inappropriate—exactly a case where a poor idea is better left unsaid.
ことわざにあるように、下手な考え休むに似たりと諭された。
As the proverb says, I was told that a poor idea is better left unsaid.
