Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
Three siblings, Anna, Ben, and Cathy, share a room with a bunk bed and a single bed. Anna sleeps on the top bunk, Ben sleeps on the bottom bunk, and Cathy sleeps in the single bed. Their parents decide to surprise them by rearranging the furniture while they're at school. They move the single bed to where the bunk bed used to be and vice versa. When the siblings come home, where do they think their beds are located? Provide a brief response.

### Response:

When Anna, Ben, and Cathy come home, they would initially think their beds are in the same positions as before because they weren't there to see the furniture being moved. Anna would expect her bed to be on the top of the bunk bed, Ben would expect his bed to be on the bottom of the bunk bed, and Cathy would expect her bed to be the single bed in its original position.

However, after the parents have rearranged the furniture, the actual location of the beds would be different. The single bed would now be where the bunk bed used to be and vice versa. So, the actual positions would be: Anna's bed (the top bunk) would now be located in the spot where the single bed was, Ben's bed (the bottom bunk) would be in the same new position as the top bunk since they are part of the same bunk bed unit, and Cathy's bed (the single bed) would be where the bunk bed was originally.

Practically speaking, each sibling would find that the area where they sleep is in the place of another's. Anna would find her top bunk where Cathy's single bed was, Ben would find his bottom bunk in the same new location as Anna's because they share the bunk bed, and Cathy would find her single bed in the spot where the bottom bunk use to be.
