Why does the author keep mentioning brille role as a father

If the author didn't mention Brille's role as a father, an important message would have been missed and it would have resulted irrelevant.

Explanation:

Therefore, a member of a group must perform this role even if he or she is not the real father. It is called structuralism and systemic theory. Both are social sciences theories to understand groups dynamic. They also say that if a group has no "caregivers" the groups are destined to broke and its members will look groups that can provide them those guarantees, or else they would perish.
