I am watching this serie. I told in other post. Now, I think you must to have watched You, it is avaiable on netflix. After I was disappoint because the Beck's die, exist a new character in new season. In the second and third season of the series You, the character called Love is shown to be so harmless and appearing to be a new victim of Will and in a short time everything is ready to fall into place until some twists and turns occur.
What we can learn from the series itself is that sometimes we need to preserve some data about ourselves when we're using our social media. The protagonist of the series a maniacal serial killer, Joe Goldberg gets information about his victims very easily with just a few clicks on the social networks that people themselves leave open.
Knowing a little about the past of people we have just met can prevent us from falling into traps and preserve our lives. Sometimes the person can be on the run and you don't know anything.
Be careful who wants to control your life in any way and have a lot of power over you. There is no reason for a new person to want to obsessively and insistently enter your life knowing so little about you.
Know yourself and your intuition, sometimes as much as someone seems to want to help us and for our good, our intuition is warning us that there is something wrong with that person. The so-called red flag and the information that someone gives you can make you discover that person's true intentions with you.
