The answer to the riddle is “the living room”. The term “ghosts” generally refers to the spirits of dead people, and they are often depicted as haunting or occupying certain places. In popular culture, ghosts are often shown to be associated with places that are dark, creepy, or abandoned, such as graveyards, haunted houses, or dungeons.
On the other hand, the living room is a space in a house where people typically spend most of their time while they are alive. It is typically the place where people gather to relax, entertain guests, or watch TV. Therefore, the joke in the riddle is that ghosts avoid the living room because it is a space associated with living people and not with the dead.
This riddle plays on the idea of ghosts as supernatural entities that are usually associated with places that are gloomy or eerie. By suggesting that ghosts avoid the living room, the riddle subverts this common trope and presents a humorous twist. It also highlights the fact that ghosts are often depicted in popular culture in ways that are inconsistent with reality and are simply a product of human imagination.
