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

### Instruction:
At a birthday party, Jack watches as his friend Sam hides a gift behind a potted plant. Later, while Sam is distracted, another guest moves the gift under a chair to make more space. Meanwhile, Jack goes to the bathroom and misses seeing the gift being moved. Upon returning, where will Jack expect Sam's gift to be hidden and how does this differ from the actual location?
Provide a very brief response.

Jack will expect Sam's gift to be hidden behind the potted plant because that is where he last saw it before he left to use the bathroom. Since he was not present when another guest moved the gift, he has no reason to believe that its location has changed. Jack's expectation is based on the information available to him before he left the room, which did not include the gift being moved. Therefore, his mental representation of the situation is outdated.

The actual location of the gift, however, is under a chair. This location differs from Jack's expectation because the change in the gift's position occurred outside of his awareness. Without having observed or been told about the movement of the gift, Jack has no way of knowing that its location is no longer behind the potted plant.
