https://en.wikipedia.org/wiki/Aporia
In philosophy, an aporia (Ancient Greek: ᾰ̓πορῐ́ᾱ, romanized: aporíā, lit. 'literally: "lacking passage", also: "impasse", "difficulty in passage", "puzzlement"') is a conundrum or state of puzzlement. In rhetoric, it is a declaration of doubt, made for rhetorical purpose and often feigned.
aporia 的意思是：討論達到了死胡同，所有人都走到一種困惑的狀態。 通常的結束方式就是「我要回家吃飯」作結。
