I've interacted with a couple of INFPs and I wouldn't describe our interactions like that way... More like we're both equally wordy about what we're interested in once we get to know each other somewhat. I'll listen to an elaborate fantasy (and then comment/joke on the feasibility). Then I'll go on about some elaborate explanation/summary of something (and they'll comment on its accuracy/ moral implications).
As a whole, I'm really drawn to IxFP imaginations and strong viewpoints of the world, but INFPs seem to be less likely to be offended by my jokes (and more tolerant of my social gaffes). I don't think they are as amused by my antics as I am by theirs, but I suppose what I contribute is listening skills without bringing lots of my own emotional baggage?
Definitely a type with which there is more to talk about if we agree on subjects because we can hash out the details of how we reached this decision (as oppossed to say... most ESTJs I'm been acquainted with because they won't really elaborate or explore something already in mutual agreement- so it is acutally much more enlightening to oppose them). Very hard to communicate with when disagree in final judgements.
