Great thread--thanks so much to all of you insightful WSers!
I find the snip above very interesting. Cindy is trying (with a blizzard of words) to hide the fact that she had a history of calling around for KC when KC didn't come home at night--she claims that this line in her screed is based on some long-past event.
What I believe actually happened: at some point before she posted this to MySpace, Cindy got tired of the run-around from KC and likely started calling and interrogating as many of KC's friends as she could find. Maybe one/several of KC's friends slipped and told Cindy what KC had said about her (and why she said she was no longer living on Hopespring with the parents at that point). Or, maybe Lee caught wind of the anti-Cindy stories and reported back to his mom. Either way, this made Cindy angry, so she posted the public MySpace in part to tell everyone her side of the story

eek: at the thought that her reputation among KC's friends would have been a concern right then--but that seems in character for Cindy).
More important, she very likely grilled KC's friends about the last time they saw KC, and whether Caylee had been with her. If Cindy had heard from friend after friend after friend that yes, they had seen KC at x place, but no, in none of these cases had anyone seen Caylee, that would have escalated her panic substantially. Looking at the call logs from the following thread (
Cell Records revisited. - Websleuths Crime Sleuthing Community), Cindy and KC had by far their longest post-June-16 phone conversation/fight (up to that point at least) the morning of July 2 (22 minutes--all previous calls between KC and the Anthony parents had been surprisingly brief, considering the circumstances). Two hours later, KC sends a long line of texts, one by one, to a list of her friends--I'm not sure whether we've seen the content of these texts, but if not, could she have warned all her friends not to take Cindy's calls? (We know she warned someone--Jesse, I think?).
I'm not sure if this adds anything--but this just brought the probably events of that day (IMO) to life for me, and may explain how Cindy realized that Caylee was actually missing (i.e., she wasn't just off with KC). Now, why Cindy didn't act at that point...???
