You can't fight a 10-year-old, but man these kids really make it tough not to want to pick them up and toss them out the subway doors. What level of hell do these turds come from? If I had to guess I'd say that lady isn't their mom, but something like a nanny or someone from a government agency. Whatever she is, she's not helping one bit.
Warning: Very NSFW language from these 10-year-olds.
