Q:On a Sunday morning, I was driving down a road and saw something I couldn't believe. A little girl, less than two, was pushing her stroller across the road. It was Sunday morning and traffic was not heavy. I stopped my car at once and ran toward her. This little girl knew enough to run from a stranger. I tried to catch her in order that I could get her out of the road. Suddenly her father came running down a hill across the road from where I had parked my car. He ran right to her and caught her up, saying "bad girl" to her. I picked up the stroller and gave it to him. The father grabbed the stroller and walked toward where he came from without a word. I went back and sat in my car for a few minutes with my son. My hands were shaking and tears were about to run out of my eyes. "Do you feel cold, Mom?" asked my son. I just shook my head. After this happened, I thought about how thankful I am. Even though the father didn't say thank you, I feel that I did something good. Doing something for someone else is pleasing, even when it's only a matter of being in the right place at the right time. I didn't really "save" her, but I feel like it was important that I happened to be there. It is sad that I was the only one who stopped. It really made me a little disappointed that no one else stopped to help. The author thought that her help was _ . A) really necessary B) worth praising C) not welcome D) not useful
