I knew this would happen.
Do you know how many INTJs I've had to patch up after an INFP ruined them? I always want to pick up the lifeless, broken INTJ, put it under my arm, carry it down to the INFP, present it to them, and scream at them, "You idiot! You BROKE it! Is this your idea of fun, of personal growth, of playing around? Explain yourself!"
They connect too well on the Fi level, and the INFP can make the INTJ all but useless for any practical purposes. Worst part is, they often aren't even loyal to them after reducing them to that state, leaving them to find their own way out. Bastards.
