Elephant in the room

Have you ever experienced that there is a clear issue but no one in your group will discuss it because the topic makes you all uncomfortable? That is called the “elephant in the room.” In English, an “elephant in the room” means an obvious problem that everybody knows about but no one wants to talk about. The first recorded use of this term was in The New York Times on June 20th, 1959: “Financing schools has become a problem about equal to having an elephant in the living room. It’s so big you just can’t ignore it.”
