DS5 is a PG kid and I would say that he is definitely more extroverted, when he is around others that have anything in common with him it all (whether it is running around, playing games, etc.) I have never really seen him be shy that I can think of, and he enjoys being around people a lot. That being said, he also will enjoy going off by himself and reading and going on the computer...but doesn't do that is much when there are people around as he typically spends time with them.
