In a library, there are five people: Karen, Lucy, Mike, Nancy, and Oliver. Karen takes a book from the shelf and starts reading at a table. She then leaves her seat to find another book. While she's gone, Lucy sits down at the same table and accidentally spills coffee on Karen's book. Unaware of this, Karen returns with a new book and sees the damaged one. What does she think happened while she was away?

Provide a very brief response.
Karen, upon returning and finding the book damaged by coffee, would likely think that someone spilled coffee on her book during her absence. Since she left the book on the table and found it in a different state than she left it, it is reasonable for her to deduce that the incident occurred while she was away, and since Lucy is at the table with the spilled coffee, Karen may suspect that Lucy is responsible for the damage to the book. Karen does not have the full context of what happened, so she is left to infer the events from the evidence in front of her: a damaged book and Lucy's presence at the scene.
