Hmm, I kinda relate to this too though. I'm darkside so/sx though (weaker so stronger sx than usual), and I think it's just that sx wants to zone in on something which is why we come off as drifty or awkward. I dunno, I can get kinda either energized from group interaction when the people stimulate me enough and I feel satisfied with the interaction or I can get kinda down if the conversation was dominated by other people and I didn't really get to pull anything from it. Even in a really small group (3 people, the closest thing to 1-on-1 without not being 1-on-1), I remember going to the gym the other day with two of my friends (xxFJ so/sp girl, ESFJ either so/sx or so/sp guy - he's basically all social and nothing else haha I should start a typing thread for him) and I had to repeat myself FOUR times until the ESFJ guy stopped interrupting me right as I started saying something. Thank god I had the gym to channel my negative energy into after that.
I know The Great One kept pushing the fact onto me that I liked my cliques because I was so/sx, but really all I care about doing is building relationships. I personally prefer 1-on-1 interaction because it allows me to show all sides of who I am rather than just one, which is what group interaction forcibly limits you too a lot of the time. With just one person, I can show my serious sides and share more meaningful sentiments, while also feeling more free to have fun and do what I want without being collectively judged. If you're in a group to socialize, all you can really do is go with the flow (I mean, you can suggest things but it has to be judged by the whole group which is kinda terrible) unless you REALLY want/need to do something else - in that case you just leave them all to do their own thing.
