In life and over time we will encounter evil, malicious people, without values and different epithets that we can assign to them... and the best thing is to try to stay as far away as possible in our closest family interactions, and to be very objective regarding this issue... especially with our children, often the admonitions towards a new friend whom we know does not have good behavior are taken poorly by them, until they realize that the guidance was accurate. As you say, it is better to be cautious of those unhealthy interests that only seek to harm us, the best thing is to keep away and avoid any risky situation, very interesting your topic, thank you for sharing from Venezuela.
