One may say it's how much open minded one is, but this video of Chastain's love for durians:
and watching how so many others couldn't take even the smell of durians, makes me ponder on another fun idea:
Trust.
That this can be used as a test for trust. A measure of how trusting a person is or can be. Not how much we can trust that person.
Of course, this doesn't work on those eating durians growing up.
In trying to understand how repulsive durians are to these people, I could relate the smell to that of garbage. But I've never thought of it that way before. I had "trusted" durian's taste to be GOOD when I was little, a time innocent enough to be very trusting.
Chastain's love for durians could indicate that she's a very trusting person. That's my first impression, unless somewhere else in her brain has a screw loose.
