Your words pass like wind by my ear. Splendid. Quite splendid.
For a speech that was heard and immediately forgotten.
Chinese original
君之言,如风过耳,甚好,甚好。
Why it works
The formal register does the mocking. Wind past the ear leaves nothing behind, and the doubled “splendid” sounds like a polite dismissal rather than anger.
