Between Two Question Marks

When the teacher comes back, he tells the girls that he likes them, and they all run away. When they return, they find that the food tray has been overturned in the cafeteria, and that the girls have been mean to each other ever since they began hanging out with each other. The girls decide to tell the teacher what has happened, but they are interrupted by the arrival of another student, who comes in just before the bell rings. The girl asks who the student is, and the girl tells her that it is the student who came in just 1 minute ago. She also tells the girl that the girl's clothes are too long, and she is afraid that the boy will grow taller, so she will have to buy bigger clothes.
