A few thoughts to consider:
Cindy, I believe, left before 7:30 sometimes, according to her statement. Yes, I do believe she said she could hear breathing through the door. Quite believable in my home. I'm embarrassed to say you could hear me breathing all the way across the house or on a different floor, if I am sleeping.
George could have been speaking generally, such as on the last day I saw her there was breakfast, feeling her hug, seeing her wave, getting into the car, never to be seen again. I could say we put her into the car, saying goodby for the last time and mean that I said good by and she was put into the car. It is quite easy to say things differently when a year later or feeling such emotion as they obviously would be on this anniversary day. My heart went out to them. It must be a hard day.
It was 5 months from the time Cindy realized she was missing until she was found. I don't get the issue with that at all. 12-7=5. People speak through their own perception. Today, Cindy spoke through tears but she spoke her truth, IMRO. She became aware of Caylee missing in July and was found in December. Logically, she now knows it was June, not July. But for her it became July, when she was made aware. That is the date that registered in her brain, and understandably.
