Lost Dog

Today I lost my dog. He ran out into the forest, and he did not come back. After 15 minutes I began to get worried. However, I did not go to the forest to look for him. The sun began to set, but my dog had not come home yet. I decided I had to go search for him. I walked deep into the woods, but there were no signs of my dog anywhere. Although I looked for hours, I never retrieved my pet. I arrived eat home defeated. I wanted to cry, but when I opened the door my dog had returned home!
