【明報專訊】Bentley is a musician who lives in an apartment. He has neighbours upstairs, downstairs, and on all sides. "He's nice, but I do wish Bentley would pipe down," one of his neighbours said. The others agreed, saying: "He would be a better neighbour if he'd pipe down." Alas, none of them will get any rest as long as Bentley plays his horn (管樂器) — and the expression pipe down means to be quiet, to speak lower, or to stop making noise. Oh, did I tell you? Bentley's wife is a drummer in a rock band. "I wish she would pipe down too!" someone said.
