Part A: Read the following passage from "Two Kinds."
Over the next year, I practiced like this, dutifully in my own way. And then one day I heard my mother and her friend Lindo Jong both talking in a loud bragging tone of voice so others could hear...
"She bring home too many trophy," lamented Auntie Lindo that Sunday. "All day she plays chess. All day I have no time to do nothing but dust off her winnings." She threw a scolding look at Waverly, who pretended not to see her.
"You lucky you don't have this problem," said Auntie Lindo with a sigh to my mother.
And my mother squared her shoulders and bragged: "Our problem worser than yours. If we ask Jing-mei wash dish, she hear nothing but music. It's like you can't stop this natural talent."
Based on the conversation between the narrator's mother and Auntie Lindo in this passage, which word can you infer would best describe their relationship?
