Why might have the author decided to include the scene with Dinitia and the swimming pool? How might this

experience be a defining moment in Jeannette's childhood?

Hello. You forgot to mention that this question is about "The Glass Castle".

Answer:

The author decided to include the scene with Dinitia and the pool to show how the blacks who already suffered a lot of discrimination were more tolerant of people with bad life situations. This is a defining moment in Jeannette's life, because it allows her to befriend and allows her to recognize tolerant, friendly and good behaviors.

Explanation:

The Glass Castle is a book written by Jeannette Walls, where she tells the stories of her childhood, living in a dangerous environment, with dysfunctional parents and intense family problems. In this story the author Jeannette tells how the other children refused her company at the pool because they said that she lived in the garbage (the house she lived in was very old and worn out) and that it would be a source of illness, since she had a family situation and economics so bad. Jeannette is very sad about the situation, but finds a friendship with Dinitia who says that she can use the pool with black children.

Jeannette is well received by black people who use the pool, since they understand what it is like to be discriminated against, besides, she makes a good friendship with Dinitia, which influences her childhood positively.
