Sometimes, if a kid wants a candy bar in the grocery store, you tell them "no." Same for a new toy.
So a parent should create arbitrarily unfair situations to teach their child that life sometimes isn't fair?
That seems sketchy to me.
I mean, first of all, it's kind of unnecessary. Life's unfair enough as it is. Even for a kid, there are going to be plenty of situations where there's some kind of obstacle in their way of getting what they want. So just telling them "no" to fill some kind of unfairness quota seems really redundant to me.
Second, that's not really how unfairness works in the real world. When there's something in the way of what you want, or if something unfair or unjust happens to you, there's always a reason for it. There's always some chain of events that led to that happening. Like, using an example that would involve a kid, let's say that a family is going to go on a vacation to disneyland. But then the car breaks down, or someone gets sick or breaks their leg, and the they can't go. That's unfair. That's just a bunch of random things happening that screwed over a kid's chance to go to disneyland. But there was some kind of logical chain of events that led to said injustice. And learning why unfair things happen and understanding the larger context that they happen in is just as important as understanding that you can't always get what you want.
Third, it might have a really negative unintended side effect. It might make a kid willing to put up with being treated unfairly by authority figures when they don't have to. And that's not a very healthy trait for surviving as an adult.
All in all, it would make more sense to me to simply wait for a natural injustice to pop up and let it run it's course. Don't say no to the candy just for the sake of it, say now when you don't have enough money or you know it would make the kid sick later.
When an adult id speaking, the child should be quiet and wait their turn to talk. I understand that while a very young child may not grasp the concept of waiting their turn, an older one should know it.
That's not really how conversations between people play out in real life, though. I mean, yes, sometimes you should be letting the other person complete their thought, but then sometimes it's acceptable if not necessary to interrupt them.
And in my experience, I think that conversational etiquette is the kind of thing a kid learns through peer interaction, not from their parents.
In short, the kid shoudl know that the world does not revolve around them and that they need to take other people's thoughts and feeling into account when they act.
Well, yes, obviously.
