For a safe encounter.
The person does not instill trust in you: Always rely on your instincts and don’t stay there. Watch for signs that will inform you about the integrity of your interlocutor that might tell you that there may be something fishy about him. For example, even after many meetings that were very interesting, the person still does not want to give you her phone number at home. This person may have something to hide. Is she married or already involved in another relationship? You be the judge!
