Finally, the bus arrived. Joe jumped on and gave the driver his fare. As he sat down, he checked to make sure that he had enough money for a ticket. Last week Joe had seen a western called Trail of the Seven Sioux. He didn't know what was showing this week. The bus was behind schedule
, and Joe was afraid he would be late--but when he got there, he didn't have to wait in line. He found a good seat just as the lights dimmed.
What is a schedule?
