It's a fantasy role-playing game.

DM: You are Vax Vax'ildan, a half-elf rogue . You are the member of the famous group of adventurers. Previously, Being the adventurers they are, they took it upon themselves to leap out into the forest of the Vesper Timberland, found and hunted down this hydra, fought it, and upon slaying it discovered that there was another group also hunting this hydra. An actually sanctioned group, and hunting this hydra is considered illegal in Vasselheim unless you had actually been contracted to do so.
DM: Exactly. You glance about the room as you're walking forward carefully, looking at the floorboards, looking at the tapestries on the walls, looking for anything that would be out of sorts, and your eyes very keen to find anything out of the ordinary. The room thankfully does not appear to have anything specifically trapped. It seems fairly safe.
Player: Oh. Okay. And those are doors up there?
DM: Yeah. Door to the right, door to the left.
Player: Would that check include the doors themselves?
DM: I would say with a natural 20, yes. The doors both also seem to be functional doors, not designed with any sort of trap attached.
Player: All right. Pressing my ear to the door on my left.
DM: Okay. Listen to it. Perception roll.
Player: So many. Six.
DM: Seems fairly quiet.
