How do you explain the change in Ma

It is Saturday, and Norman won’t be taking the field as Richmond’s new center-half-forward. He hears his mother laughing in the kitchen. He goes in to discover she is no longer covering her face in white powder. She looks her usual self.

She is facing the situation and being herself.
