For me, it's relating to other people that's the main one. My sensory issues are next-to-non-existent, and my executive functioning appears to be all right, even though I'm very clumsy.
But relating to other people, communicating, empathising, getting along with the crowd, small talk, that's still very difficult for me, and I've arrived at a point where I limit my social interaction outside of work. At work, I limit it to the professional level, and I don't really join my co-workers on the breaks anymore (we can kinda sorta choose our own breaks, and we can certainly choose where we sit [there are several stories in the building, and only one floor has a canteen]). So yeah, this is still a problem for me.
