Looking at the dates of June 1, 2, 3, and 4 with fresh eyes I really get a feel for what was going on then.
Keeping in mind that CA had recently found the pics of KC at the no clothes party that took place end of May, KC's perpetual work claims were wearing on CA.
Also keeping in mind that CA told her work peeps that she was hoping to have bonding time with KC during her upcoming week off really sets up a volatile environment considering -
Sunday, June 1, KC feigns working all day - does not get home until past midnight.
CA contacts her AM, PM afternoon 2X and 8:51 PM.
I can just hear how the conversations may have gone down, "How long do you have to work today? (CA doubting that KC is working)
Afternoon, "Are you almost through?" Again at 4:29 PM, "Nobody works this many hours, get home, I'm tired and have been looking after Caylee all day, would like to see you and so would Caylee, my turn to rest, etc."
8:51 PM "Get your arse home now. You don't care about me or your daughter you are selfish and an ingrate. I don't appreciate this one bit and you're going to have to shape up or ship out."
Even after this 9PM call, KC does not get home til after midnight. The activity of June 1 set up the first major fight surrounding Caylee's care. The 8:51 PM call was a precursor to the inperson fight that probably took place on June 2.
IMO the only reason KC had Caylee with her on June 2 when she went to TL's, was because of the shake down with CA that occurred over the events of June 1. KC is home by 7:00 PM on June 2 but calls first (I wonder if she tried to feel out if she would be able to return to TL's without Caylee).
June 3 is telling. KC is taking her mom out to dinner to pacify her and show her she does care, blah, blah blah. Do we know if this dinner really took place?
June 4 KC is right back to business as usual. KC calls home at 3:45 PM.
Then CA is calling her repeatedly beginning at 2:25 AM for three calls total. KC does not return home until well after 3:00 AM - the wee hours of June 5 (which begins CA's birthday).
IMO this got CA's day off to a bad start.
I'm just recapping what ya'll have already figured out and agreeing that the events of these dates turned up the heat for what was to come.
