I think you are a mind reader and you can evaluate what is happening in the group around. I have seen even this community also that people's sharing their very personal moment and forget about Facebook. It is like each one posting their own personal dates to public.

Unknowingly they are getting trapped in the system and exposing their life to public. Which could be very vurnable to their life and wealth.

You have reviled a very important point in our daily life.
