Yeah what was that all about??? Its like she is literally enjoying this. She likely thought she would get away with it and the cops would believe every word she said. She wasn't even crying!
There's a lot going on when people smile. Smiles don't always mean someone is happy, contented, friendly... or any of the other positive emotions we associate with smiling. Closed mouthed smiles mean something very different from open mouthed smiles. People sometimes smile when they're in pain, embarrassed, surprised, frightened, angry... stressed, anxious...or, even if we feel under the pressure of too many people looking at us all at once when we're feeling guilty about something we've done, imo.
The "rest of the face" cues us in on what's really going on emotionally more so than the mouth. When MB is smiling, the rest of her face is
not smiling, imo... there's very change to her facial arrangement other than her mouth and that makes me feel she's not happy or enjoying herself at all.
She came into the courtroom with that expression already set on her face... almost fell while tripping and what do we see? She's able to hold the same expression as she walks to her seat... and then all through the hearing we see it until something is mentioned that is too sensitively close to her own knowledge of her guilt and then we see what's
really going on inside her head. She has no control for a moment over herself and her eyes dart around in guilt and fear. That's it...
that's what's going on inside her, behind that "painted-on doll's smile" she's been wearing like a shield. (imo)
Imo, she's consciously putting on a mask to hide behind but, in reality, she's frightened, self conscious, embarrassed and resigned... she got caught doing something horrible and, in spite of all her lies trying to redirect the guilt of it, she knows
everybody knows she's the one who did it. Imo, her expression is conveying so many uncomfortable feelings about her present circumstances, that her guilt "is literally written all over her face."
Some of this speculation is not JMO... but comes from studies; ie... "why do people smile, what do smiles really mean, studies on smiling, etc)
But, the interpretation of what
MB's smiling, is
really all about is JMO and so could be wrong.
