因为害怕隔墙有耳,我们连说话也得放低声音

yīnwèi hàipà géqiángyǒu’ěr, wǒmen lián shuōhuà yě děi fang
dī shēngyīn

We hush our voices for fear of being heard

我们谈话时没有旁人。你是怎么知道她的话的?—隔墙有耳,你是知道的

wǒmen tánhuà shí méiyǒu pángrén. nǐ shì zěnme zhīdào tāde huà de – géqiángyǒu’ěr, nǐ shì zhīdào de

We were alone when we talked. How did you know what she said? -Walls have ears, you know
