There is a guy in my class that I suspect is an ESFJ and he talks about things in his personal life quite a bit. Even things that I wouldn't share with normally anyone, he talks about them like it's nothing. It might be from the perspective of an INTJ who tends to be a bit secretive and usually talks about things if the other person does, but to me he's just really open about a lot of things. It would be things from his parents to his passions to what he did one summer to anxiety disorder(s) he has. He will even complain about things to people he doesn't know that well, I guess it's just because he needs to rant about it for a while. Is it common for ESFJs to be that open?
