Why doesn't Adeline get tram fare like her siblings

When the issue of tram fare comes up, Niang is outraged that the children have gone behind her back and forbids them from troubling Aunt Baba or Ye Ye again. Soon, Adeline realizes that there is “a new family hierarchy within [the] family” (40) with Niang at the very top. Though they agree to stay loyal to Ye Ye and walk instead of buckling under Niang, one by one they slowly give in. Adeline remains resolute, walking to school in the rain and cold, though she feels isolated when her siblings are invited into the “Holy of Holies” to collect their allowances each week.
