Once I passed the old building, behind which there was a loud, unkind laugh and a mournful squeak. Approaching closer, I noticed guys from three people who mocked the poor puppy. Feeling anger, began to approach the company. Seeing me, they ran. The puppy whined piteously and paved the way to my feet. I picked it up and took it home. There he fed and watered the baby. Soon the sound of opening doors was heard. I was frightened, because I did not expect the parents to come soon and did not know how to explain the appearance of the dog in the house. At first the parents were unhappy, but after hearing the story about how I saved the puppy, they softened. Looking at the sleeping child peacefully, I really wanted to leave it. To persuade parents for a long time did not have to and since then we have a black dog and pleases all members of the family.
