At the end of a call I've made within the past few weeks, I asked what happened to "Dana" (from ... somewhere), but after the call I realized that Ian must not have known exactly who I was talking about because he commented just generally on the fact that some callers fall off over time.
The reason I called about her in particular is because the last I ever heard from her, she was
dying. She had called in to discuss how Medicare was leaving her to die because she wasn't "poor" enough (or something like that) to get what she needed, in their eyes, (even though she had been reduced to living out of her car). She called one more time after that but I don't recall it sounding like her situation had been resolved.
To put it shortly, I'm worried that the reason she stopped calling is because she's dead.

Edit: This seems to have turned into a general "Where are they now?" topic. Maybe all these posts that are not about Scott the Bigot need to be moved, or the topic title needs to be changed.
