I couldn't possibly

Neutral Polite

What it really means

A ritual first refusal of an offer — the last slice of cake, a favour, a gift. Tradition allows the other person to insist once or twice, after which accepting is perfectly polite.

Chinese explanation
面对好意(最后一块蛋糕、帮忙、礼物)的仪式性初次推辞。按惯例对方会再劝一两次,那之后接受就完全合乎礼貌了。

Example conversation

A: Take the last slice — go on. B: Oh, I couldn't possibly… well, if you insist.
A:最后一块你拿去——别客气。 B:哎,这怎么好意思……那,恭敬不如从命。
