On my way home from school last Friday, I saw a little dog on the sidewalk looking hopelessly. I was held it firmly up in my arms, took it home and feed some milk to it. However, my mom was unwilling to keep them, saying there was enough pets for us, two cats and a dog. I begged my mom not to let it go. Finally, we agreed that it would be deciding by my dad, whom didn't return home from work. Just then the girl and her father drove near, searching for their lost pets. When they thanked us taking care of the dog, I felt very happy.
