Have you ever forgotten where you put your keys or walked into a room and couldn’t remember why? In the United States, people often use creative ways to talk about forgetfulness. One of those ways is by using metaphors. A metaphor is when we describe something by saying it is something else. It helps make big ideas easier to understand.
When people talk about having a bad memory, they don’t always say it directly.
