The words that we must say. The things that they tell us we must not say. The rules that come with being a human. We didn't choose this.
We weren't given the choice to be brought up in this world. But they blame us for our choices. Things as simple as the words we use.
Now why would that be such a big deal, that you poison your child with a bar of soap? There is no residue of the words once said, and this punishment certainly does not fit the crime.
Crime is a strong word, isn't it, well, then it does not fit the action. Soap is not for the children who say undesirable things.
