He doesn't intuitively know how to interact with others. Every bit of his social skills are intellectually processed vs. natural, hence observing his friends doing something and then imitating them as whatever they're doing must be what he's supposed to be doing in order to play whatever it is they're doing - it likely makes perfect logical sense to him. Sounds like you're literally going to have to show him how. Step by step, explaining your actions & then what his should be in return in whatever activity you're doing or conversation you're having so he gets the idea of back and forth interactions. Not sure if it would be advantageous or not to tell him that was the objective of your lessons ?? but you could just go through the process w/o explaining why you're doing it if you think he'd react better. Even just kicking a ball back and forth might be a good start if he's taken to copying his friends like he's their shadow. It'll teach him to pay attention and wait for the ball, then return the kick while you wait. Something like that may break his habit of trying to do the exact same thing as someone else at the same time they're doing it if that's what he's doing now. Well, it makes sense to me that it would, anyways. I suppose it depends on the kid.
