I still don't know whether or not I'm gifted or just a high achiever, but I am definitely an introvert. I stay up late every single night to have my alone time after my kids and DH go to bed. I was more "outgoing" as a young child but around 5th/6th grade that changed - not sure why. I can engage people in conversation no problem (unless it's on the phone, then I have to psych myself up) but I prefer 1 or 2 people and hate having to be around more people than that all at once in a social setting. Even after having a one on one conversation for more than like an hour, I'm fried - done.
My DS who is possibly EG seems to trend toward introversion - it's hard to tell for sure because he is often "high" with his sensory issues and will talk to anyone (including strangers - ugh). I do think he feels shut down by his peers somewhat due to what the OP mentioned.
My DD who is not identified but I think is MG, seems more extroverted to casual observer but she does have a shy streak (which I know isn't the same as introversion). She doesn't go off and play by herself as much as her brother does.
