Cale has that thing. That introvert thing.
That thing that signals to all extroverts in the area and some people who are interested in social interaction without being extroverted: "Adopt Me!! I Cannot Stop You!!!"
Bonus: I think Slacker Life-Nim is like Cale, in that extremely introverted way, and struggles to enter a space that is full of people (and thus is unable to approach Cale).
