It's a fantasy role-playing game.

DM: You are Caleb Widogast, a human wizard . You are the member of the famous group of adventurers. Previously, However, they cannot find anything, and Jester skips away. Molly buys a huge, silly tapestry of the Platinum Dragon.
DM: Well, let's go ahead and see. Rogue proficiencies. It's a simple ranged weapon. You should be. I'm pretty sure you are. Yep, simple weapons. You are proficient with the short bow. "Who's going first, if you don't mind me asking?"
Player: Let me show my daughter how it is done.
DM: "Of course, understood." Hands you one of the short bows off of the side and three arrows. They're all right in their construction.
Player: Watch my form and technique. I pick up the bow, and I take the stick thing. I pull it back like this.
DM: "Oh-- I--"
Player: Yeah?
DM: "No, continue."
Player: (sneezes)
DM: Which target are you aiming for?
Player: The farthest one, obviously.
DM: The farthest? All right, with disadvantage. Add your dexterity modifier.
Player: Oh.
DM: I do not think you're proficient--
Player: Aww, no, not at all. That is a three.
DM: Well, as a wizard, you might be, actually. For simple weapons. Nope. No, you are not.
