@
consentingadult, this is an interesting assertion. I work with an SEI-Fe and I will admit that I get the strong impression that she never goes negative. She's always upbeat, positive and encouraging. Except, of course, when she expressed shock and dismay at one of my jokes. I now limit my interactions with her in duration and frequency for the sake of harmony, since I doubt if I can ever amuse or entertain her like an ILE can, but she's a wonderful person.
On the other hand, I also worked with an SEI-Si and she and I never really got to a point in our mutual dealings that was positive enough to see any value in each other. :( To me, her cheerful sunniness seemed 100% phony.
To be fair, the SEI-Se never went negative unless it was in relation to some failing of mine, which she instantly shared with everyone she met.
But that's Conflict and not a reflection on SEI's in general.
