It's a fantasy role-playing game.

DM: You are Beauregard Lionett called Beau, a human monk . You are the member of the famous group of adventurers. Previously, Molly and you remain outside while Jester and Fjord deceive their way into the house disguised as Prucine and a crownsguard. Caleb, Nott, and Ulog sneak in the back door.
DM: No, most everybody's at the gala right now. You can see in the distance, you can see the party's still going on. The music's still playing from the distance. There's still drinking and revelry muffled in the distance, the din of the crowd giving this low (distant cheering).
Player: If I get a chance, I want to try and lose him.
DM: He's not following you. He's just watching you as you walk. So you're going to try and move out of his eyesight?
Player: I'm going to try and move around, yeah, and move out of his eyesight.
DM: You move out of his eyesight.
Player: Anything? Do I notice any following me?
DM: Perception check.
