“Remember, you can’t completely trust everyone you know.” There is one rule you can try to remember: Strangers are all people you know little about and don’t know as well as you know your closest people. If you don’t know them well, you can’t be sure if they are good or bad and if they would hurt you or do something bad to you.

    There are people who look very good, are nice, smile and talk nicely, but are actually bad and can hurt you.

    And there are people who are frowning, talk loudly, look gloomy, scary, but they are actually very good and can help you. There is no way to know who is good and who is bad if you do not know the person very, very, well! As you know me. Their mother smiled.
