a leopard never changes its spots本性難移

前半句是老諺語，後半句一把扭成毒話，雅和髒撞在一起，殺傷力翻倍。

A leopard never changes its spots and ...

翻臉互罵時才會聽到；對朋友開玩笑要看清關係，正式場合別說。

A leopard can't change its spots. ／ Old habits die hard, and so do old insults.

口語

leopard 和 spots 重讀，後半句加快帶過，才夠狠。

He swore he'd be on time, but a leopard never changes its spots. 他發誓會準時的，可江山易改本性難移。

一個反問把答案擺上桌，再用兩個詞收尾，像判決錘落下來。

Why do you think he's been ...ing? He knows!

揭穿、逼問時用；對當事人說太狠，日常別輕易出口。

Why do you think he keeps doing it? He knows. ／ You think it's random? He has known all along.

口語

Why 和 knows 重讀，中間那串壓扁快速帶過。

Why do you think the boss keeps checking your reports? She knows. 你以為老闆為什麼一直查你的報告？她心裡有數。

一句訴說撞上一句冷嘲，接話人把對方的希望當場折回去。

Some things never change

嘆人事難改時用，多帶無奈或挖苦；對剛受挫的人說會顯得刻薄。

Some things just stay the same. ／ You can't teach an old dog new tricks.

口語

Oh, well 拖長，some things never change 平穩收，冷味就出來了。

He still texts at midnight. Some things never change. 他還是半夜發訊息。有些事是改不了的。

把一場人際戰爭壓縮成「讓誰跟誰反目」一句話，結尾再補 do you hear me 強行要回應。既展示 turn someone's mind against someone 這個實用搭配，也把潑辣勁寫足。

You'll never turn ... against me, do you hear me?

跟人當面攤牌、警告對方別挑撥關係時用，語氣強硬；冷靜溝通的場合用會顯得對抗。

You will never set him against me, do you understand? ／ Don't think you can turn him away from me.

口語

turn Tony's mind 連讀，against me 重讀，do you hear me 逐詞壓低。

You'll never turn the team against me, do you hear me? 你休想讓整個團隊跟我作對，聽見沒有？
