Did you notice how when BOTH her parents set her up for their little lessons on sharing (even though ALL of them were shown screaming and crying at one point about not wanting to share), she passed with flying colors. I loved that she just sat there happily and quietly after Adam and Danielle go on about how they have to keep her close to them, and observed while she had to wait last for her turn in playing with the robot. Even Parker, who was actually whining and not wanting to share got a turn before her. And they didn't even show it, so who knows if she actually got to play with the robot.
And then Adam in the playroom with the cookies. I legit thought he only had four and was going to make Riley hand them out but not get one to teach her, but not the others, a special lesson about sharing. But once again, Riley exceeds the low expectations of her surprised parents and has no problem passing out the cookies.
I've said it before, but it is wrong how Riley has always been labeled the "bad" one or the "difficult" one by her parents when she's really no better or worse than the rest of them. Yeah, she wasn't wanting to share when they were outside, but ALL of them were not wanting to share. Danielle had to call out Olivia a few times too, but no special lessons or labels for her. Same thing with the painting. Riley gets chastised, but they were all whining at some point and Danielle's sister had to step in and end it. Speaking of, Krystal/Kiki has been shown to be much more firm and effective than her sister. And I think at one point all of them were painting and Danielle was holding Riley back, again reserving punishment and the lesson for just her.
And Adam can be so utterly useless sometimes. When they were outside he's talking about how Danielle couldn't handle the stress of the girls fighting (emphasis from both on Riley), but he does absolutely nothing at that moment to help. He does manage to tell Danielle he's going to be there to help, but not that second apparently. And as previously noted, they both sit there and do nothing while the girls continue to fight.
