I had been dreaming of have a pet of my own. Therefore, my parents thought it was an burden and didn't agree with me. One day, I came across a homeless dog that itself looked worn out and in great pain. I get close to it and found its ankle hurt badly. Seeing this, I carefully picked it out and took it to the doctor's. Just after three day, the dog recovered. To my delight, my parents finally allowed me raise it. We got along really well but became good friends. Whatever I went, my dog always kept me company.
