The 10 year old little girls's parents should be the one smacking her upside the head in that scenario. People need to learn to be cordial no matter their age.So what's next some little 10-year-old girl runs her mouth and you're just supposed to run up and sucker punch her in the side of the head also?
Lesson 1 don't run your mouth to someone who can beat you up.
Lesson 2 understand there are consequences for beating someone up.
Both lessons were forgotten in this video and both people are suffering the consequences (assuming the old dude was being disrespectful). Seems like the natural worse case scenario played out on this one.
