I am in complete agreement with you. Nothing "snapped" imo. She's always been this way they just couldn't see through it. MOO
I don't think anything snapped either...........I really, really think that she was drinking or on prescription drugs........and something happened to Caylee and she was too scared to call the police because she was worried she would be tested.
With her history, she KNEW no one would trust anything she had to say
