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

### Instruction:
A group of friends - Mary, Jane, Peter, and Paul - go hiking together. They stop at a fork in the trail and decide to split up, with Mary and Jane going left and Peter and Paul going right. Before they part ways, they agree to meet back at the fork in two hours. During their hike, Mary and Jane find a beautiful waterfall and decide to stay there longer than planned. Meanwhile, Peter and Paul return to the fork after two hours but don't see Mary and Jane. What do Peter and Paul think about Mary and Jane's whereabouts? Provide a very brief response.

### Response:

Peter and Paul, upon returning to the fork after the agreed two hours and not finding Mary and Jane, might think that their friends have encountered something interesting or beautiful, such as a scenic spot like a waterfall, which is common when hiking, that could have prompted them to prolong their hike. They could consider that Mary and Jane lost track of time while enjoying their surroundings. Alternatively, Peter and Paul might also consider the possibility that Mary and Jane faced a minor delay or setback, such as taking a longer trail, becoming momentarily lost, or stopping for a rest. Given that hiking can be unpredictable and that there was a plan to meet back at the fork, Peter and Paul would likely wait for a reasonable amount of time before becoming concerned, trusting that their friends had a good reason for their tardiness.
