We're all rather in shock.
I am thinking of how much regret I have that I didn't pursue her friendship more. And I'm thinking of what fun she could be, and how smart and savvy and verbal and witty she was. Irreverent, but not unserious. She had a gravitas that made her light and lightening moments seem all the more to be celebrated. It's only in the context of a sense of familiarity with angst that delight rings so deeply, with such profundity. And she did delight in much---it doesn't take having been her best pal to know that.
Goodbye, PAS. You know you've left a big ghost among us.
