For months, Aida and her three closest friends had been waiting for a new movie to come out. The movie was based on one of their favorite books, and they promised they would see it all together and then go out for pizza. On the movie's opening weekend, Aida had a last-minute emergency and wasn't able to go. The others decided to go anyway because they had really been looking forward to it.

She felt like no one even cared that she had missed out on their plans.
