Exactly this.^^^^
Hey Casey,
1) Get better at lying. I actually think you've gotten worse at it since back in 2008 when you were lying about having a job, nanny, where Caylee was, and who all of your made-up friends were.
2). Get better at learning what normal people (non-psychopaths) would feel about their child's death. Squeeze out some fake tears like you did at the trial and talk about how sad you are still and how it haunts you at night that you "don't know" what Caylee's last moments were like (I mean, you obviously do know and aren't troubled by them, but just pretend you don't and that you are troubled).
3) If someone asks what Caylee would be like now just lament the fact that you'll never know because she was taken too soon. Maybe stay away from cursing while talking about your deceased baby.
4) Learn your daughter's birth year so you know she'd actually be 11 right now, not 12.
5) Don't speak in such weird sentence structures and phrases. It draws attention to the fact that something is really off with you and also comes off as disingenuous (which it is).
6) You've had over eight years to get your story straight. Pick one, learn it, and stick with it. The drowning theory worked with at least some people (jurors), so that's your best bet (obviously people with brains won't believe it, but it was proven that some idiots will).
7) Pick the dirty clothes up off your floor before letting an AP reporter/camera person in your room.
8) Scratch all of that. Since you're incapable of mimicking a normal human being, just stay out of the press and public eye.
