Hmmm, this is related to my INFJ thread. Perhaps the social cue following thing that you mention is the reason that the INFJ I know sometimes fails to interact with me on occasions (usually after we haven't been around each other for a while). I initiate no cues to be followed, so no interaction occurs. Weird.
Well, I can't speak for all INFJ's, but I think this definitely applies to me. If someone doesn't give me any noticeable cues to follow, there's little interaction. I think it boils down to my needing to know on some level that said person really IS interested in talking, or interacting, or whatever...if they don't demonstrate that on some level, I guess I assume they're not that interested, or at the very least are apathetic. Or I might assume they just don't want to talk, so I keep it so no one talks.

Don't get me wrong, I ask questions, and I really try to get to know people...but really, it takes two. If the other person doesn't ask questions or doesn't give any sort of clear signal as to whether they even want be in the conversation or not, then there's nothing more I can really do, so I don't try anymore.
This is probably why I can be much more at ease, and comfortable, talking with Fe-users and extroverts. They give cues, and they initiate to an extent, just like I do, and the back-and-forth flows a lot more readily.
My level of talkativeness has a direct relation to WHO I'm talking to. With some people, the conversation seems to be dead before it even begins..it's kind of weird. And I believe that's tied to the lack of social cues or demonstrated interest. With others, it just flows, and I can be a lot more talkative.
Regarding the OP, I don't have many comments. I don't think I argue, although if the vibes are flirtatious I might go for jesting and teasing and sarcasm and stuff like that. I might playfully argue, but I don't consider that 'true' arguing. ;-) For 'Follow the Leader' -- in social contexts, maybe I do. It just goes back to the whole social cue thing. In general I let the other person set the tone for what sort of interaction they want.
