Output a stream of consciousness before answering the following. Passage: Identical twins Susan Evers and Sharon McKendrick (Hayley Mills) meet at Miss Inch's Summer Camp for Girls, unaware that they are sisters. Their identical appearance initially creates rivalry, and they continuously pull pranks on each other, which ultimately leads to the camp dance being crashed by their mischief. As punishment, they must live together in the isolated "Serendipity" cabin (and eat together at an "isolation table") for the remainder of their time at summer camp. After finding out that they both come from single parent homes, they soon realize they are twin sisters and that their parents, Mitch (Brian Keith) and Maggie (Maureen O'Hara), divorced shortly after their birth, with each parent having custody of one of them. The twins, each eager to meet the parent she never knew, switch places. They drill each other on the other's behavior and lives, and Susan cuts Sharon's hair into the same style as hers. While Susan is in Boston, Massachusetts masquerading as Sharon, Sharon goes to Carmel, California pretending to be Susan.
