Iâve experienced a bit of all of these.
Iâve experienced all of these as well. One facet of these models that attempt to classify and organize behaviour (that IMO is not addressed often enough as part of these models) is that they are âcontext drivenâ. It seems to me that we are all capable of responding in each of these ways depending on the context, the circumstances we are in at the moment. That being said Iâm guessing we each probably have a reflex response that gets used more than the others because we find ourselves more often in circumstances where that response is the âgo toâ one so to speak. Thatâs my observation at least.
Also, for what itâs worth, I see âfawnâ as a subset of âfightâ rather than itâs own categoryâŚand hereâs why. I realize that this way of considering comes from behaioual technology NLP and is based on directionalization. I donât recall Fight, Flight, Freeze, Fawn as part of the NLP model howeverâŚit was modelled in a different fashion.
Fight is a âmoving towardâ behaviourâit engagesâaggressive
Flight is a âmoving awayâ behaviourâit disengagesâregressive
Freeze is a âno movementâ behaviourâit neither engages nor disengagesâremains static
Fawn is a âmoving towardâ behaviourâit engages, not as aggressively as âfightâ but still there is active engagementâŚitâs not disengaging like âflightâ nor is it âno movementâ like âfreezeââŚitâs active and âmoving towardâ in nature
Does seeing âfawnâ in this way make any practical difference?..probably notâŚyet this is the sort of thing my brain likes to do. 
Reminds me of the quote, âKeep your friends close and your enemies closer.â Fawn, haha, moving towards the threat with a âcharmâ and âdisarmingâ behavior.
Moving towards and moving away I like here because they are energetic and in some ways easier to relate to than âfight or flightâ. Also fits with Right Distance Right Depth as a strategy for primitive brain balancing.
