Im not really sure how to feel about this one, I think both parties are in the wrong here, but I have allot of sympathy for the Driver. Both of my parents drove school busses for years and it's a terrible job most of the time. That, however, doesn't make all the of the drivers actions right. I would be willing to assume that this girl has a history with the driver before this encounter.
*EDIT* To skip to the actual short fight go to around 7:55-8:00
