Answer:
One morning, three friends went for a drive. They came across a forest and decided to go inside it. They got out of their car and began walking. Unfortunately, they got lost without a clue of how to get back, and to top it off it began raining. They saw in the distance a hut, so they hurried on over to it.
After knocking on the door, an old man answered. They explained their situation to him. He was kind enough to let them wait inside until the rain stopped and then he escorted them out of the forest, back to their car. They called their other friends and told them about how they got lost, met an old man, and were driving back. They then safely went back to their homes.
