What can we assume about the character of the father because of her reaction to this moment?

Lizabeth’s “world had lost its boundary lines” explains us that the idea of men do not cry has changed. “Men do not cry” that is the boundary Lizabeth is talking about, and losing this boundary is her father crying to her mother. Although, that misbelief of “men don’t cry” is based on what we commonly hear when we are children, when fathers tell their children to grow strong. However, it cannot be taken as literal, because men do cry. It is true that men have a biological “responsibility” to look tough, and the traditional foundations of a family are based on this belief. Nevertheless, this biological “responsibility” only offers a complementary pillar to the overall idea of the family. Family life starts to be affected negatively when the entire foundation of a family is based on this narrow thinking.

Is there more to this?
