@Angelina: let me give you an example. I have someone who reports to me who I figured out after a few meetings that they are insane. They're pretty pleasant and kind to me but I noticed this person is always complaining about everyone to me. Of course this person must also complain about me then if they're complaining about other people that are even nicer than me. And I started to notice they get upset easily (holds facial expression) over minor things but tries to hide it. Major red flag. I caught onto this person within 1 month of meeting them just 3 times. I went to check their marital status on the system and of course, this person is single and has their mother as their emergency contact.
