Probabilities and prediction

Reflecting back on Clarissa's situation, I think my chances with her are going to be low.  She was most likely calculating her probabilities too, that is if she was even planning anything.  It's odd, I still can't type Clarissa, she most definitely is an extrovert or else she is a really well disciplined introvert.  I can't really decide whether she is a Thinker or a Feeler.  She did think that I was pissed off at her during Econ 4, but any feeler would have disregarded me after those interactions, perhaps she's borderline T/F.  I'm still wondering what kind of person would just rush out of class like that.  Is she a J or a P, she definitely needed time to think after I told her how the classes were structured.  She's still a mystery, I hope to get to know her better.
