People have they daily routines, their jobs, families, safety, car, gym, friends, barbecue, police protecting them, doctors healing them…
And then one day all that is gone and they need to go out to find water to drink, food for their kids and defend their home, their world is finished, and some new world is came.
In that situation people change, some adapt, other not. And people react different. You never know how your first neighbor will react. Actually you can be prepared and ready, but still YOU can be surprised with some of your emotions and reactions when SHTF, not to mention how other people who do not know what world prepper means will react.
So be prepared that even people who are “normal” will become not normal because it is not normal situation.
