Another great idea you should adopt when raising children is to create a code that lets them know who is safe to be near them.

在撫養(yǎng)孩子時(shí)，你應(yīng)該采納的另一個(gè)好主意是創(chuàng)建一個(gè)代碼，讓他們知道誰在他們身邊是安全的。

If someone other than you came to pick you up, they probably know the secret code they were given in advance, so they know it's safe to go with them.

And if that person doesn't know the code, you're not allowed to go anywhere with them.

如果那個(gè)人不知道密碼，你就不能帶他去任何地方。
