This isn't an ESI/LIE conversation, but this thread seems to be the most appropriate place to say this without starting a new thread.

At the moment, I have two ESIs in my life. One is an ESI-Se, and the other is an ESI-Fi. They feel very, very different to me, despite me liking both of them a lot.

The ESI-Se feels more like an Activity partner, as if she were an SEE, except she's not as flighty as SEEs.

The ESI-Fi feels more like an EII Semi-Dual to me, except she's able to influence me to do things, which the EIIs are not.
