I'm sure it did happen years ago and like someone said...we just didn't have the internet back then.
I know this isn't to the level we're speaking here but this happened in my family recently:
the day after our wedding (so 2 weeks tomorrow) there were still 25 or so people around our summer place, camping and extending their vaca.
Supper was being served and there was a huge variety...meatballs, lasagna, turkey, ham, salads, fish, hamburgers and hot dogs and plenty of everything. My 11 year old niece wanted to go 5 miles down the road to the take out place for chicken fingers. Her mother, exhausted from the busy week, told her no, there was plenty available..to just have what's made.
My niece kept it up and hounded her parents and grandparents, and they all agreed, there was enough available, she didn't need to go anywhere else...well, she flipped. She told everyone they were fucking idiots, she hated them, they all were so mean to here, and told her grandmother (who is beyond good to these kids) that she's a fucking dummy and she fucking hates her and shoved her and stomped out (my niece was cursing like that).
She was in her room for the night and her parents left early the next morning.
The grandparents (my parents in law) live down the street and get the kids off to school in the mornings, make breakfast for them, have lunch ready, etc. When my niece arrived, they told her she wasn't allowed in until she apologized....she lost it again and said she didn't owe anyone an apology. It's 2 weeks now and she STILL hasn't said sorry and she's still not allowed in her grandparents' house.
It's becoming a huge family issue, everyone is taking sides and discussing it in great detail and arguments are developing among everyone...some say it should just blow over and some say she should be made apologize, and she's sitting back laughing thinking she's going to get her way - which, sadly, she probably will.
THAT is a huge lack of respect and if it does just "blow over" she'll only get worse, knowing she can get away with things like this. I don't think she's the only kid 'out there' these days that behaves this way and THAT is why people like this bus driver and other 'strangers' get the harassment they do...it's not stopped at home, so they feel they are allowed to behave this shitty way.
