At first, it was sunny, the mountains were beautiful and he felt happy. But time passed quickly and soon it was getting dark. He realized that he was a long way from his cousin's house and was completely lost. suddenly, he heard a strange noise and saw a large dog. The dog was barking and seemed to be asking to follow him. After they went for a while, the dog took the boy to his cousin's house. The dog ran off into the night and the boy never saw him again.
