Stunned by any major change or problem, the deer in the headlights is paralyzed. Seems frozen by the fear of making a mistake or provoking someone. Tries to blend in with the surroundings and fade into the background. The Jackrabbit races along at top speed, seemingly headed in a purposeful direction. When confronted with an unanticipated obstacle, veers off the path and accelerates in a new direction.
Any stimulus results in a complete change of direction, again at full velocity.
Wags tail furiously and licks whatever is in reach. Treats each any new arrival similarly. Is momentarily loyal to whoever might have a treat. Action vs Reaction Okay, so these are archetypes. You still see people like this at work every day.
