I think part of social awareness is coming to understand the audience you are interacting with. If I talk to an MD/PhD about a topic of interests, I use different language than I use with the 5 yo who lives next door. I wouldn't be understood in each context unless I could adjust my interactions.
I agree! This is exactly what my DS9 does!
He used to complain that kids his own age don't understand what he says because of his advanced vocabulary. (They used to tease him by calling him an "alien".) As he developed more social skills over the years, he has learned how to adjust his language depend on the "target audience". He carefully chooses "words" that typical kids his age use when he interacts with his peers in class, but talks more like "himself" among older peers and adults. He has a deficit in his social skills, so he needed to be taught this particular copying skill. Shellymos, it seems to me that your son has pretty well-developed social awareness for his young age, and since he is a very social kid, I think he is trying to relate to his peer by "writing like the other kids".
