Kindness is not as important as kindness. Nature refers to the person who gave birth to you and the person who raised you. Kindness naturally means that your kindness is heavier and greater, because in the human world, it takes a long time for people to grow and mature, at least 18 years. In these eighteen years, a person who only gave birth to you but never raised you at all, in my opinion, is just not worthy. After all, it's not just money, but also energy, education and love. Family ties are born from childhood, not mainly by blood relationship. People are defined as higher animals because they have IQ and can think. At the same time, emotional and family ties can produce unbreakable family relationships in years of getting along. Therefore, even if they give you life, it is not as heavy as the feelings you have paid to support you.
