As a high school teacher, I can attest that most teenagers are pretty awkward with each other when gathering in large groups until they get to know everyone well. So, that part seemed fairly normal to me. I believe the "elephant in the room" was the superiority, arrogance and entitlement that the individual teens seem to demonstrate--Josie included. It seemed to me that the parents of these kids, since they had made the conscious decision to have their children "lifted", shared & perpetuated this sense of superiority for the most part. It was clear by the questions that were asked by the girls that higher intelligence & social graces were not always achieved when "lifted". The pettiness & the willingness to mistreat anyone or thing NOT "lifted" was also
disconcerting. Nonetheless, Josie seemed to develop some friendships close enough to warrant sleep-overs as she got older. As for all the other social interactions mentioned in the question, each individual seemed tense & somewhat artificial with the end goal being for her or him to gain something from the other person. Very awkward & sad. I would have to say that the only genuine social interactions seemed to be those that Josie & Rick shared when they were young.
