Just last week, i was walking down the street with my mother, and i again found myself conscious of the english i was using, the english i do use with her. we were talking about the price of new and used furniture and i heard myself saying this: “not waste money that way.” my husband was with us as well, and he didn’t notice any switch in my english. and then i realized why. it’s because over the twenty years we’ve been together i’ve often used that same kind of english with him, and sometimes he even uses it with me. it has become our language of intimacy, a different sort of english that relates to family talk, the language i grew up with. how does tan build a central idea of her story in the excerpt?
