Def cant deal with a closed off person. If you cant be vulnerable then you cant be honest. And from that point youre disingenuous and disconnected. No and no thanks. I feel like those who cant express themselves fully, for whatever reason, miss out on growing. You dont know what type of conversations, answers, epiphanies you can have with others if you could open up. It also wreaks of insecurity. That "have a wall!" "guard up!" mess is so dramatic. Grow up.
