Bring a doorstop. Keep your door open when you're in and that sends positive messages to your neighbours that you're friendly.

别关上门。保持你的门是敞开的，当你在屋里的时候，开着门会给邻居积极的信号——你是友好的。

We're gonna have to get a doorstop tomorrow.

我们明天得去弄一个门挡。

Otherwise, it is nothing more than a paperweight or a doorstop.

否则 这本书就只不过是一个镇纸石或门垫。
