I was a substitute school bus driver for a year or so and it was no picnic. I never had anyone treat me like that though. They were noisy and misbehaved sometimes...mostly the middle school kids. The elementary kids were noisy, but not badly behaved otherwise...in general, and the high school kids just slept all the time. lol. I didn't have much trouble though. If they behaved well, I'd let them listen to the radio and I would tease them...like a funny game where I'd play classical music or opera and they'd howl...."Oh-h-h-h-h-h noooooooo." And everyone would crack up laughing. I'd pretend like I was serious. Then I'd change it to something they liked. I'd let one kid choose the station and the next time another kid got to do that. So, it seemed to keep them busy and it was a reward for good behavior.
I got one kid who was very troubled...a rough type and always getting bus tickets. She had to sit behind me as her "punishment." (that was put on her by the regular bus driver) I didn't feel very comfortable with that...thought she might pull a knife on me or something.
So, I let her be the one to control the radio which was on my left side within her reach as long as she sat nicely and quietly. That worked wonders. I talked with her a little bit when I could. She kind of attached herself to me and looked up to and bonded with me a little bit. I didn't know if it would work or not, but it seemed to get her focus off of causing trouble with other kids and the like and she found out that I liked her and that she didn't need to do those awful things to get attention or get noticed. (Or whatever the reason was she got snarky with people before)
This kid in the video though....wow. To have the capacity to be that disrespectful toward someone in charge is just over the top. Sometimes, these kids with no empathy can't ever be reached. And sometimes they need some kind of positive thing to happen before they go off. I think they act like that because that's what they hear at home and are treated badly from the get go....at least in part.
