No focus change - and that one, none. Look at her. Seriously, look at her. My fucking cat could take her.
Now you see your comment could be interpreted as sexist.
You cannot attribute sugar and spice to girls and slugs and snails to boys as if it was real.
Some kids boys and girls, are extremely dangerous to innocent people. I don't know why but buses and cinemas seem to bring out the worst in them at least IME. Obviously lots of young people are lovely and usually polite, some are troubled and this girl is probably troubled, granted. She does not appear to be a girl who is a stranger to violence and aggression. She looks like she's seen a fair few fights and is used to getting her own way by being aggressive.
Personally my worst nightmare re being attacked / robbed in the street is young kids. They are more likely to carry knives than older people and whatever you do to fight them off / protect yourself will easily land you in trouble.
This girl was behaving in an extremely dangerous and aggressive way, if she's anything like some of the kids round here the chances are she could be carrying a knife.
Now if, after the uppercut she was wearing a neck brace, lacking teeth and her face all swollen then the situation would be different and I would feel very differently about it.
That driver knew how to throw a punch, he had probably had some boxing training at some point and if he had intended to really hurt her he could have done. As it was he gave her a comfortable ride that looked dramatic but, as you can all see from the videos, didn't do her any serious injury.
I would be very interested to know how the passengers in the bus who didn't know either of them felt about it.
