I usually just listen to the ENTP, watching him dig his hole deeper and deeper.
By the way, did I ever dig to deep concerning yourself ? What you said I figured out some time ago by myself with the only intp I know. I often encounter the problem that he speaks my language just too good and then I get into a rampage totally forgetting about him being somewhat alike but somewhat different.
My apologizies, if I did so. You can use this thread as an universal green card, if I do it again. It is really not on purpose
