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

### Instruction:
In an office, four coworkers - Jane, Mike, Laura, and David - share a communal refrigerator. Jane brings in a purple lunchbox with her name on it and places it on the top shelf. Mike, not realizing it's Jane's lunchbox, moves it to the bottom shelf to make space for his own food. Later, Laura accidentally spills coffee on the bottom shelf and moves the purple lunchbox back to the top shelf to clean up the mess. Finally, David rearranges the fridge items, placing the purple lunchbox in the middle shelf. Where does each coworker believe the purple lunchbox is located?
Respond very briefly.

### Response:
gpt
Jane believes her purple lunchbox is on the top shelf because that is where she originally placed it and she has not witnessed any of the subsequent moves. Mike thinks the lunchbox is on the bottom shelf since that is where he moved it, and he's unaware of Laura's and David's actions afterward. Laura assumes the lunchbox is on the top shelf because she moved it there herself to clean up the coffee spill and doesn't know about David's later rearrangement. David knows that the purple lunchbox is on the middle shelf as a result of his own action of rearranging the fridge items.
