Parenting, the only subject where a parent gives exams every moment and never gives himself 100/100. Yet generation to generation we feel our parents were better than us as a parent.
As a parent every parent carries guilt when they grow older and recollect their smallest mistakes in parenting.
What a humble beings?
And as a child the child carries complaints about their parents till they grow up to be parents too.
What a late realization?
How phases of life make us thankless beings, ignorant beings and humble beings as we progress and all just in one life.
