Me too! In many group situations. Also when walking with others, if the path is wide enough for 3 and there are 4 of us, guess who's all by himself behind the others? Or in front of them. And that can be despite continual effort to NOT be the one left out. It's like the others know what I'm doing and it all becomes an almost overt competition as to "who belongs the most". It's pathetic, in one sense.
I am now aware enough of it happening, that if I concentrate 100% on not being the one left behind, I can sometimes manage to stay with the group. Then what happens is that because I have focussed so much on observing the movements of the others, predicting where they'll move to next, constantly readjusting, then I have totally lost track of what anybody has actually said!
It seems that it will never be instinctive, always effort. What happens if you get a group of 'us', the out-of-synch ones all together? Would the least extreme on the spectrum somehow manage to group with each other?
This seems to me the core sympton of AS: not naturally belonging with the herd.
