Hmmm. I've been (maybe incorrectly) assuming that Cindy, who first (1) posted on her myspace page on July 3 re: all of the lies and deception Casey had put her through, and who later (2) is talking directly to Casey during the first 911 call while she thinks she's waiting for police to come on the line and doesn't seem to know she and Casey are being recorded, and says the business about already having given Casey 30 days, was simply being honest with her daughter at that moment in time because she didn't think anyone else was listening in on their conversation. Whether or not she meant she'd given Casey 30 days to let her see Caylee or to move back in with Caylee, etc., I don't know. Then, as you point out, it is AFTER the 911 calls that Cindy tries to disregard that Casey had moved out/pretend that they hadn't moved out, moving from there to pretend that Casey & Caylee just left for some bonding time, and so on spinning the facts to mean whatever she needs them to mean from there on out...
So to me, it's the one (and maybe only) honest set of comments/exchanges between Cindy and Casey I've heard.
I still can't understand who Cindy thought had been dead and in the trunk, if she didn't suspect it was Caylee.
