The title sequence establishes the main characters as a boy and girl divided by a tree, representing gender stereotypes. It shows them arguing in cartoons and then in person, with the boy starting fights and the girl reacting maturely, suggesting they will argue throughout the film. Shots of their conversation show the girl angry while separated by the tree. A shot through a door shows the girl's stereotypically feminine pink room as she makes her bed neatly, accompanied by gentle music, establishing her character.
