It was almost time for the annual masquerade at the high school you go to, and the student council has placed you in charge of getting costumes for everyone to wear for that night when it actually happens as you prepared for it. Luckily, there was only one costume shop available this time of year.
Your task was to pick up a box which contained costumes that would match the theme of the masquerade your school was throwing, so the student body president sent you to pick up an order for that theme at the costume store you arrived at. After the student council got their costumes, they would let you have one free. You tell the clerk who was dressed as a witch about the order you were going to pick up from the store, and then she responded by pulling out the box full of costumes.
