I have a general rule, that if a dog can learn to behave in public, your child should be able to as well. And hopefully parents hold their child to a higher standard of behavior than a dog.
"Barn kids" are probably some of the best kids to be around because (usually) they've been taught to have respect for the horses, and they understand that the barn/farm is not
their personal jungle gym to play in. They also come in handy for getting horses used to all sorts of crazy things while also being respectful enough to stop what they're doing when asked. Horses, in turn, tend to be good teachers, because they don't listen to the whining or pay attention to the crocodile tears that some kids use to get their way.
When kids grow up with the knowledge that they have to actually earn things by working
for them, that they don't automatically get a prize just for showing up or doing what they're supposed to do anyway, and that there are times and places where some behavior just isn't acceptable, they usually grow up to be responsible and respectful adults.
Sadly, though, there are an awful lot of "precious snowflakes" being raised to believe that they can do no wrong. Their parents are convinced their child is a sweet, angelic, wonderful, innocent "little person" and always
have an excuse for the child's bad or disrespectful behavior.
It must be something in the brain chemistry that makes parents unable to see that their little cherub is just a manipulative little brat - or, they want to be their child's "friend" all the time, so they make a lot of threats of punishment but never follow through with any of it because they're afraid their child may not like them anymore.
Even some of the people I know with older kids (tweens and teens) are so desperate to be the "cool mom/dad" that they let their kid get away with more and more stuff and then blame everyone else when the kid actually gets into serious trouble or gets hurt.
The end result is a generation of selfish, entitled kids without any sense of being held accountable for their actions, no idea of negative consequences, expecting to be rewarded for everything they do, and knowing their parents will always come running to their defense when they get into trouble.
