One morning, Karan and Megha went to the movie theater. They were going to see a new scary movie that just came out today. When they got there, Karan asked for two tickets to the scary movie.
"I'm sorry, we aren't showing it yet," said the person behind the counter.
"Yes you are! It's gonna show in fifteen minutes!" Megha exclaimed. She pulled out her phone and went to the theater's website. "See? It says it's showing at 10:00."
Karan realized they made a mistake. What was it?
