have someone safe

This is easier coding, but less safe because there's no absolute guarantee that someone may not have deleted one of the breakout subgroups manually, so you miss deleting higher-numbered groups.

这是比较简单的编码，但是安全性比较差，因为不能绝对保证用户没有手工删除过一个断接子组，所以会漏删编号较大的组。

Although that special someone was supposed to have called you long back, to let you know of their safe arrival, your phone is quiet.

虽然“那个人”本应回你电话，让你知道他已经安全到达，但是你的电话仍然静悄悄的。

In some homes, owners have built safe rooms-special places where they can go for protection should someone break into the house.

有些人会在家中建造一个安全的小房间，当有人破门而入的时候，就可以躲到这个安全的地方寻求保护。
