I encountered this line of discussion, in an alt news site, and thought it would be applicable, here, because of the sense of emergency, which seems to follow NT people, everywhere they go, everything they do, on an everyday basis.
The three typical responses, in case of fear or an emergency:
fight (hyper-aggressive, combative)
flight (kinetic movement, work in progress)
freeze (hypo-active, has to be told basic things.)
Each one of these emotions has it's own, separate language, allowing you to relate to each kind of person.
It doesn't literally have to be the end of the world (but, they won't want to be told that.)
