How realistic is Melinda's first day at highschool?

It sounds like a fair representation of the first day of high school. At Merryweather High, ninth graders are herded into the cafeteria for a freshman orientation. Melinda notices janitors repainting the school sign. Merryweather’s mascot, due to complaints of lewdness, has just changed from the Trojans to the Devils. As she enters the cafeteria, Melinda describes the various cliques the grade has broken up into. Her friend group from last year has disintegrated, and each member has joined a separate clique. Melinda, however, remains alone.
