At l;east, we have to LEARN to deal with such people because they may not alwys be total starngers.

Imagine that "Janice" is your wife, plus you have a teenager with "issues" , imagine the kid has autism or such... and you find yourself and family in a survival situation.

We need to upgrade our psychologial efficiency of tolerating tough conditions and tough people. That should be one of the survival skills to learn before SHTF. Imagine yourself sandwitched between two self-centered persons, each sees the whole world from an extremely narrow and completely different window. If you do not maintain your calm , your brain and nerves will disintegrate quickly.
