I'm WAY more extraverted than my mom though, who is ESFJ. She's more of a people-person than I am but in the sense of pure extraversion I'm a hundred times 'worse' than her. She can be all people-person-y but then she always needs to go home to her own space where things are her own way etc, and when she does her tasks she prefers to do them alone. If someone comes up and starts to chat with her while she's doing the laundry she'll be happy to chat and pleased to see them, but she wants to bustle them off all the same cos she can't get on with things while people are around. Maybe that's related to my pure extraversion, in that as long as they're around she can't focus on the task at hand, but I think it's more just that she actually does like doing these tasks, and doing them alone. She's said before that it's when she "clears her head out". She does get tired too, after say a dinner party or whatever, whereas I never do. After a party I feel like I'm ready to conquer the world.
Most EJ's I've known have liked being around people but generally don't tend to invite them back home very often - they go to work, go to school, college, church, bars - whatever - and get their people fix but seem to treat their home as a sort of private space.
