That has been my experience, too, @FDG. That vid that Told Ya posted above seemed more like comedy.
I will say that I see the Aggressor in ESI's. It is more of a Wait-and-Advance-one-small-step-at-a-time aggression, though. They seem to do a lot of watching before making a small move. (Which is actually the approach I find to be best for me.) But they do make that move.
The relationship dynamics are a result of the ESI's 3D Se (I clearly see the situation that I'm in right now, and I don't like it) and 2D Ni (I have a hard time predicting which is the best of multiple choices, so the heck with it, I'm gonna do something. But something small, so I don't risk much if I screw up.)
vs.
the LIE's 3D Ni (I have a really good idea of where each one of these options are going to lead) and 2D Se (but I feel I'm not entirely certain of the facts of the present situation).
