It might be the incredulous tone she uses to make it seem like something she's 100% done on camera is absolutely absurd, and anyone who believes or suggests it is an idiot for thinking it's possible. She took this tone when responding to a question about fitting in an Uber, like the asker was a moron to think she could be so humungous that she couldn't fit in any vehicle that she wanted to. Except she used being too swollen to fit in their vehicle as an excuse for missing different appointments before. She also uses this tone when asked if she's sitting on a mattress on the floor, as if sitting on a mattress on the floor was the wackiest thing she'd heard in her life, as if she doesn't have a documented history, with video proof, of her having a mattress on the living room floor of their previous home. It was a very conspicuous mattress, obviously. She feels like she can just say something didn't happen, and it didn't happen. It doesn't matter if everyone saw it happen.
