情话是傻子说给疯子听的
[qíng huà shì shă zi shuō jĭ fēng zi tīng de]
A metaphorical expression, it states ‘love talks are conveyed by a fool to a madman’, suggesting love-related conversations might sound irrational or silly both from speaking and hearing sides. It may also imply how deeply engrossed lovers can get, seemingly detached from rational reality.
