A lesson of power and the unfairness of the world
This is a good moment for one of the most important life lessons a person can have:
I am larger than you, I can beat you, and you can't beat me.
I have money to buy food, and you don't, without me you would starve.
I am older and I believe that I can judge better than you. If you don't agree, we can discuss, that's good. But I have the final word, and you don't, because I have the power.
In life, many decisions of how to live come down to personal belief, and there might be no good reason why your child should share your belief.
It will be bitter, but it will make the world sweeter later on for your child.
