My dad is an LIE and my mom, as best as I've ever been able to figure is an SEI, conflictors. Of course there's plenty of grey areas in typings, and also a lot more to long-term relationships than socionics. You can work around the conflicts of a relationship and learn to respect the needs of the other. Of course that's not to say that things don't get awkward or weird. There's more than a bit of that with my folks, but they do love each other and have made it work all these years. Socionics is "working", there's just more to it than that is all.
