If you have a secret and want to tell someone about it, please take care how you reveal it. Walls have ears, it's said, and often the intimate conversations have a way of being overheard. ‘Be careful what you say, Sue. Remember that walls have ears!'
如果你要向人透露个秘密，一定要非常谨慎哦，因为 Walls Have Ears ：隔墙有耳。连我们私底下的谈话，也会经常给人窃听到的。
