At first, it's just the same apartment, the same school, and the same friends. It turns out that they've been together since kindergarten, and that's why they're always hanging out together. But then, when it comes time for them to go to a new school, they realize that people are mistaking them for each other's "boyfriends." They're tired of being mistaken, and they want to be friends with other girls. So, they go off to the new school together, and when they get there, they find that the other girls are talking to each other. They realize that they have been hanging out all weekend, and now they'll have to go back home to their parents. When they get back to the apartment, they discover that their parents have come to school early because of something that happened to them the night before. They don't recognize each other at first, but when they see each other again, they get along just fine.
