Yes, there is this distinct thing that only parents can manifest. Children are smart enough to know how much they can get away with and how much they can’t with parents.
It is the parental emotion. It is an emotional corner which is only accessed by children and adult children alike. It is a place where most kids know they can venture and win.
Parents can be as strict as they like but when it comes to that little corner only accessed by kids they drop their marching guard.
Parental duties are hard at the best of times and it is often a difficult place to be between discipline and being soft. But if the parent can be strong within that parental emotion then good for them.
We have all used or have been used in the parental emotion, it is a part of our being which is difficult to switch off.
