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 (婴儿车) 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 arts, especially music, should be part of every school's lessons at every grade level. Students would be much smarter if they had some musical experience. They could improve their classroom skills, like paying attention and following directions. People develop all these skills when they learn music. Making music also lets children use their imagination. It provides students with a chance to try out their own ideas.

    Music not only makes children better students, but also gives them something positive to do. In a music program, children can be part of a band instead of joining a gang (团伙). Parents can enjoy listening to their children's music instead of seeing them glued to a computer or TV screen. In a school band, students get to be part of a team. They can get along well with old friends and make new friends through music.

    Music builds self-confidence, too. It gives children a sense of achievement and success. Making music is something for them to be proud of, and it lets kids practice performing in front of an audience. Music gives children an opportunity for self-expression, and that helps develop their self-confidence.

    Once again, music is important because it can make children better students, give them something positive to do, and build their character. That is why music should be offered in every single grade in every school.

    I've loved my mother's desk since I was just tall enough to see above the top of it as mother sat doing letters. Standing by her chair, looking at the ink bottle, pens and white paper, I decided that the act of writing must be the most wonderful thing in the world.

    Years later, during her final illness, mother kept different things for my sister and brother. "But the desk," she said again, "is for Elizabeth."

    I never saw her angry, never saw her cry. I knew she loved me; she showed it in action. But as a young girl, I wanted heart-to-heart talks between mother and daughter.

    They never happened. And a gulf opened between us. I was" too emotional". But she lived "on the surface".

    As years passed and I had my own family. I loved my mother and thanked her for our happy family. I wrote to her in careful words and asked her to let me know in any way she chose that she did forgive me.

    I posted the letter and waited for her answer, none came.

    My hope turned to disappointment, then little interest and, finally peace. It seemed that nothing happened. I couldn't be sure that the letter had even got to Mother. I only knew that I had written it, and I could stop trying to make her into someone she was not.

    Now the presence of her desk told me, as she'd never been able to, that she was pleased that writing was my chosen work. I cleaned the desk carefully and found some papers inside—a photo of my father and a one-page letter, folded and refolded many times.

    Give me an answer, my letter asks, in any way you choose. Mother, you always choose the act that speaks louder than words.

    It was a normal school day for senior Solymar Solis until an unexpected visitor arrived. Her dad, Sgt. Carlos Solis Melendez, surprised her by coming home early from Kuwait and visiting her unannounced at Spring Valley High School in South Carolina.

    After serving in Kuwait for nine months, Melendez returned home a week earlier than his daughter expected. He held balloons and flowers in a classroom as he sat at a student's desk to blend in with the crowd. "It came across my mind like, ‘How is she going to react?" he recalled the heartwarming moment. "Is she going to be happy and run to me and hug me, or cry? That was all going on through my mind."

    As unsuspecting Solymar entered the classroom, she was soon overcome with emotion, immediately bursting into tears and covering her mouth. She didn't talk. She was just crying. She was overwhelmed with everything. She thought it was a dream.

    Melendez was a single parent so while he was deployed (调动), he got his sister to live with his daughter. When he was coming back and talking to his sister, both of them came to the conclusion that they should do something special for his daughter. Melendez and his sister got in touch with the school, and they planned this whole being-in-the-classroom thing, and it turned out perfect.

    The two are very much looking forward to some good daddy-daughter time now that he's home. "It means everything," Melendez said of being able to surprise his daughter this way. "After all the sacrifices she's made, she deserves all the special arrangements and special occasions and celebrations. I'll do anything for my daughter. I believe I'm doing good parenting."

    If you walk through the doors of one of the Smithsonian Institution's museums in Washington, D.C., you may be greeted by an unusual guide. A Japanese tech company recently sent 25 humanoid robots to the Smithsonian. All of them are named Pepper.

    Each Pepper stands 4 feet tall and has a computer screen attached to its body. Built by SoftBank Robotics, the robots are programmed to share information about the museum in which they are based.

    "Pepper is basically an experiment," Goslins, director of the Smithsonian's Arts and Industries Museum, said. "The idea is to explore and see how a robot performs in this kind of environment."

    Museum visitors communicating with Pepper. The robot can tell stories and answer basic questions. People even take pictures and dance with it.

    "The robot draws big crowds," said Allison Peck, director of marketing at the Hirshhorn. "People just love Pepper."

    According to the Smithsonian Institution's website: "Pepper gives our museum workers a new way to reach and serve visitors." For example, Pepper teaches Swahili words to visitors of the "World on the Horizon" exhibit at the Smithsonian's National Museum of African Art.

    Pepper also has the special ability to draw guests to less-visited areas of the Smithsonian's museum. When Pepper is placed in a spot, crowds are attracted to that place.

    When not educating museum visitors, Pepper stays in the Smithsonian offices, getting charged and programmed. After being charged, Pepper can run for about 8 hours at a time.

    Pepper plays an important role, but the robot "is not meant to take away human jobs at the museum," Goslins explained. "It is meant to give our visitors a more enjoyable experience while they are here with us."
