No kids
This is a riddle that we should all take a moment to think about. How is it possible that you can be a mother, but have no kids? Well, the answer is actually that you are the eldest daughter and you need to look out for everyone younger than you in the family.
Not just everyone younger than you, but you also keep an eye out for your parents as well when they need help. After all, you placed yourself as the foundation of this family and all you ask for in return is a little bit of respect. Is that too much to ask for anyone?
