Taking on a different (as you described it - more extroverted, charming) demeanour when with strangers or winging short-lived interaction would rule out Fe Polr, in my mind
meanwhile Fe creative seamlessly does so
A question I thought up was: compromise or consensus, are those priorities for you; does what the room prefers inform what you prefer?
as in, you don't have a firm grasp of your inner sentiments until you hear out those of others?
my second question can maybe relate to studies: does an encroaching deadline (or whiff of constraints?) work to energise or get you fired up about a project that may have otherwise been languishing?
