It’s like always having a feel for the 'rhythm' of any given person/situation/etc. (this is more Fe-based). I find it very easy to gauge the relative state/intent of people, and how that can extend into certain behaviors or relations. Largely in part it's an ongoing process of alignment—a gesture builds on something that happened last week, something inspires a certain reaction in me I wasn't expecting, etc; and this all forms a kind of gestalt that allows me to occupy a position without making a definitive conclusion on what any given thing "is."
