That conversation was your use of Fe. We never really only use just two functions, if we only used two functions we wouldn't be able to communicate at all. You don't have to actually connect with a person on a sheer emotional level to use Fe. You are not an ENFJ, pure emotional connections is not your thing, which is why when you do make connections with people it is on the terms of your Ti-Ne.On my own experiments, the successful conversations I've made were mainly from my usage of (TiNe). No personal/social "Fe" connections were developed but we are talking about being "comfortable with the inferior function aside from the practice of the function".
Fe is a very "disgusting" function. It should then be paired with a more(most) comfortable function...but I have never tried it. I've done (SiFe) but my voice started to shake and clearly it wasn't effective. "On the spot" is my only thought for now.
It is intellectual, but it is indeed an Fe connection.
