premise: This one is linked to being to the bus stop first , so that 's usually not a problem any more . One other thing was that the woman 's house where the bus stop is has a baby swing on the tree , and he and the younger girl try to set ' records ' by winding up the swing more than the other . Audrey always says she wins , and Paul always breaks down . She 's quite the antagonizer , and her mom has to keep yelling at her about that . Why is there a baby swing on a tree ?
hypothesis: Because it allows the girl to antagonize Paul .
