I "fit" with a group of individuals based apon need to do so to perform a function. I am adept at doing this, although I don't naturally "fit" with any particular group. I am able to assimilate the behavioural functions required to interact with one person subliminally, and so interact with them without hesitation, and so not give them the impression I am consciously interpreting their behaviour in order to respond. Even then I have limited operation of this skill, and in scenarios like long term relationships I am prone to revealing a side of myself that is nearly entirely non-verbal, strange, but apon the basis established understandable as simply an act of communicative laziness.
