壁かべに耳みみあり障しょう子じに目めあり

expression

walls have ears, sliding doors have eyes

Proverb warning that secrets can be overheard or seen even in seemingly private spaces; equivalent to 'walls have ears' but adds the Japanese architectural element of 障子 (paper sliding doors).

• 壁かべに耳みみあり障しょう子じに目めありというから、ここではあまり大おおきな声こえで話はなさないほうがいい。

  They say walls have ears and sliding doors have eyes, so we'd better not speak too loudly here.
