You pass near the high school you go to on the way to the stores you needed to go to, when all of a sudden you hear the sounds of whistles, and cheering as you pass the football field. You forgot that your high school was having an all important football game that night, while the kids were trick or treating.
You didn't know anything about football, despite the fact of getting hurt by other players on the field when they come for you, so you decide to hang out at the game, and hope that you still have time to buy stuff for Halloween that night. As you pay for entry, you took a look at the scoreboard hanging in front of the other bleachers, and saw that your school was winning against the other school, so you wanted to know what would happen next, while you got to the bleachers to sit, and watch the game.
