I second [MENTION=19719]Forever[/MENTION] on this. If anything, I'd say INFPs need to bounce ideas off more than INFJs. Te needs to vocalize their thoughts and thinking as well from what I understand, and even though it's your last function, it is still there. Ni doms instead, tend to absorb and gather information and require time to process that information, on their own. I can and sometimes do go off on my own to process things and to come up with new ideas, but it's a much slower process for me than working ideas out with other people, and I sometimes find my best ideas come from when I have others to collaborate with, so why not?
And when it comes to forgiveness or open-mindedness, true, INFPs can be very open-minded and see beyond a person's flaws, but if you cross an Fi user's boundaries or values, they can be very quick to instantly shut someone out. if I'm interacting with someone and just having a good time, and then they suddenly cross a value or offend me, I won't tell them, but I almost just shut down at that point and will basically excuse myself from the situation at that point. I won't make the situation awkward or anything and just play it off to save face, but in my head, I've written that person off completely at that point. The only way for me to really forgive that person then, is to return to Ne and rationalize the situation out to myself in my head. But even if I can come to terms with what had happened, there will always be that lingering feeling of that event always tied with that person.
