DS8 is shy and mildly extraverted.* DS4 is shy and introverted.* Both take time when they meet someone new. They observe and watch quietly and prefer not to speak. Once they've decided the new person is ok they are both chatterboxes. However, DS8 will melt down if he's had to be alone too long and seems exhausted by a lack of company. His *need* to talk to someone is what drives him to stand outside my bathroom door and chatter away even when I've told him I'm not listening. DS4 will go into his closet, shut the door and play if he's been around people for too long. I definitely see shy and introversion and very different things.
*Those are my best guesses but as these kiddos are still young- who knows.
