Iwas six when my mother taught me the art of invisible strength. it was a strategy for winning arguments, respect from others, and eventually, though neither of us knew it at the time, chess games.

"bite back your tongue," scolded my mother when i cried loudly, yanking her hand toward the store that sold bags of salted plums. at home, she said, "wise guy, he not go against wind. in chinese we say, come from south, blow with wind-poom! -north will follow. strongest wind cannot be seen."

the next week i bit back my tongue as we entered the store with the forbidden candies. when my mother finished her shopping, she quietly plucked a small bag of plums from the rack and put it on the counter with the rest of the items.

what do the interactions between waverly and her mother in the first three paragraphs suggest about their relationship?
