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 .

Answer: Because the kids enjoy playing on it .Because it allows the girl to set records .Because another swing is linked to the bus stop .Because it allows the girl to antagonize Paul .
