The Role of Children in Building a Solid Family

In a family, there's a father, a mother and their children. Their children are their fruits of love. But, what could be their role in a family? For me, they are the one keeping and letting the love within their parents to stay. They are the one sticking their family together. Because of them, their parents couldn't face back on their responsibilities. They don't even intend or try to destroy the family they stand out for. For those reasons, I think the role of children in building a solid family is that they are the agents in making it solid.
