Does he want to socialize or is he happy with the way he is?

If it's any comfort I never really socialized as a kid (I still don't, really - I have a few close friends and that's it) and I'm a well adjusted, happy adult. I've realized how much of an introvert I am, and that's just fine with me.

I read somewhere that there is an actual genetic difference between introverts and extroverts and it has to do with how we regulate dopamine (I think it was dopamine, anyway! lol). Extroverts crave more and seek socialization to create dopamine release, whereas introverts get overwhelmed by too much and find excessive socialization too tiring. I've also read that in the gifted population there are more introverts than in the general population.

Does this sound like your son? Could he be an introvert?
