What inference can be made based on what happens in “The White Umbrella”?

Part A:
B.) The narrator feels she has betrayed her
mother by telling Mrs. Crosman she wished she
were her mother and accepting her gift.
Part B:
A.) "I got out after them; and while everyone
else was inspecting the damage we'd done, I
threw the umbrella down a sewer."
B.) "Remembering what I had said to Miss
Crosman, I tried to maneuver the umbrella
under my leg so she wouldn't feel it."

The answer is the father was relieved, the officer was tired.
