And so, the next day the two children stood by their mother and listened to her instructions:
    “Most strangers are good people,” she told them, “and they won’t do you any harm, on the contrary.” Most strangers would rather help than harm. Remember this!
    Then Vasko asked:
    “What about the children who we don’t know?” Are they dangerous?
    Vasko and Nelly knew good children as well as bad children. Some of them were downright dangerous and it was better to be really careful with them and if possible not to meet them at all!
    “I’ll tell you why you need to be protected from strangers.” their mother continued.
    - Not all people are good. Remember! Unfortunately, there are people who can actually try to cause pain and do bad things to you. There are people who are dangerous. And because of them it is very important to be alert or wary!
“But how do I identify them?” Nelly asked.
