It was a pleasant Tuesday afternoon. 78-year-old Rose was brimming with excitement as she entered the nursing home with her favorite tulips (郁金香), her lips endlessly calling out to just one name—Emily!

“Emily! Where are you? I got flowers…” Rose spoke aloud when she didn’t see her best friend, 79-year-old Emily, waiting for her on the usual spot, a wooden bench on the main gate.

Whenever Rose returned from the local hospital after getting her blood tests done, Emily would run toward her with fresh hand-picked flowers. But that afternoon, Emily was not there, and the bench was empty. Emily was nowhere to be found in any of her favorite spots, which unsettled Rose even more. Just then a doctor said to Rose, “Emily’s family came hours ago while you were at the hospital... They took Emily with them. She’s not going to come back.”

The ground seemed to shake beneath Rose’s feet when she heard that. Rose went back to her room. Every step started feeling heavy, and every corner reminded her of her best friend and their laughter. Nothing but loneliness and silence surrounded Rose from all sides, and she felt her heart crack.

The scent of freshly picked flowers Emily had last left in the vase lingered (继续存留) in the still air. And beside the vase was an old recorder that endlessly played Just the Two of   Us, their favorite music they listened to every day.

When approaching the table, she noticed a note with a message in messy handwriting, “Dear Rose, please write to me at this address: Maple Ridge Ave, Springfield, VA,7…”

“Oh dear... The rest of her address is becoming blurred (模糊不清的).” Rose grew unsettled. In spite of that, Rose knew she could not just let Emily go like that. After a deep thought, she decided to reunite with her best friend.

Packing the recorder in her luggage, Rose got on the bus to start her journey to the unfamiliar city, Springfield.

Not knowing the exact house number of Emily, an idea suddenly struck Rose.

5 . I’ll always remember a lesson that I learned as a boy growing up in New York City. One day, when I was perhaps six years old, I was walking with my father on a ______ street. All of a sudden, the flow of pedestrian traffic ______ as people tried to avoid a large object on the sidewalk. To my ______ , the object turned out to be a human being, a man lying unconscious against a building. None of the passers-by seemed to notice that it was a man. Certainly no one made eye contact. As we walked by, my father — the model of a loving, ______ gentleman — pointed to a bottle in a paper bag and told me that the poor soul on the sidewalk just needed to sleep it off. Then the drunken man began to murmur senselessly. My father ______ me not to go near, saying “you never know how he’ll react.”

Yet many years later I had a very different experience while visiting a market in Rangoon. I had spent the previous 12 months traveling in ______ Asian cities, but even by those standards this was a scene of misery. ______ desperate poverty and strong winds blowing dust ______ , the locals had to live in the extremely hot climate with ridiculously huge crowds. ______ a man carrying a huge bag of peanuts called out in pain and ______ to the ground. I then witnessed an astonishing scene. Half a dozen ______ ran from their stands to help, leaving unattended what might have been the totality of their possessions. One put a blanket under the man’s head; another opened his shirt; the third one ______ him carefully about the pain; the fourth one ______ water; the fifth one kept onlookers from crowding around too closely; the sixth one ran for help. Within minutes a doctor arrived and two other locals ______ to assist. The performance could have passed for a final exam at a paramedic school.

I couldn’t help wondering, why people act differently at the similar ______ here?

8 . It all started with a simple question: “Can I paint your portrait?”

In the summer of 2015, Brian Peterson and his wife, Vanessa, had just moved to Santa Ana, California. Outside the couple’s fourth-floor apartment, a messy homeless man was often shouting on the street corner, sometimes keeping them awake at night. Peterson, 28, would pass the guy on his way to his job as a car designer at Kia Motors. but they never spoke.

One day, Peterson was relaxing in his living room, reading the book Love Does, about the power of love in action, when his quiet was disturbed by the homeless man. Inspired by the book’s sympathetic message. Peterson made an unexpected decision: He was going to go outside and introduce himself.

In that first conversation, Peterson learned that the man’s name was Matt Faris. He’d moved to Southern California from Kentucky to pursue a career in music, but he soon fell on hard times and ended up living on the street for more than a decade.

“It was the weirdest thing to me,” Peterson recalled later on the podcast (播客) Top Artist. “I saw beauty on the face of a man who hadn’t shaved in probably a year, had overgrown fingernails, and probably hadn’t had a shower in close to a year. But his story, the life inside of him, inspired me.” And even though Peterson, a graduate of the Cleveland Institute of Art, hadn’t picked up a paintbrush in about eight years, be found himself asking if he could paint Faris’s portrait. Faris said yes.

Peterson’s connection with Faris led to the creation of Faces of Santa Ana, a nonprofit organization that befriends and paints portraits of unhoused community members. Using a black-and-white photo taken with his phone, Peterson selects colors based on the subject’s personality and story, resulting in powerful portraits. He sells the large paintings, signed by both the subject and artist, for a few thousand dollars. Half of the profits go into a “love account” for the models. helping them start again. Faris used his portrait funds to fulfill his musical dreams by recording an album.

Love is a road that goes both ways. Once upon a time, a little boy named David lived with his mother in a remote and small cottage. They couldn’t afford to live a luxurious life, but were satisfied with the little they had. Every day after coming home from school, David would accompany his mother to the forest to collect what they need, such as wood, wild vegetable, fungi, and so on.

One day, when David was in the forest by himself, he came across a puppy which seemed to be all alone. David looked here and there for its owner but in vain. So he picked it up, put it under his coat and carried it home. Reaching home, he said to his mother, “Mom, I found a little puppy alone in the forest! Can we keep him, please?” Feeling David’s excitement, his mother was in two minds about whether to keep the puppy or not. She told him, “Oh, David, that’s the cutest puppy I’ve ever seen! But we don’t have much. What will we do about his food and sleeping arrangement?” David replied, “It’s OK. Ill offer him half of my meals and let him sleep with me in my bedroom.” Hearing this, David’s mother just nodded. David’s happiness knew no bounds, and he named the puppy Cookie.

From that day onwards, David and Cookie became the best friends. Cookie followed David wherever he went. When David went to school, Cookie would patiently wait outside the classroom till the classes ended. At night, Cookie slept next to David on his tiny bed and dreamed sweet dreams.

One day, Cookie and David went to school together as usual. After school, they were following the familiar routine back home when it rained heavily with thunder and lightning, so that they were running in a hurry, trying to reach home as soon as possible. The roads everywhere turned slippery. Unfortunately, David missed seeing a hole at the side of the road and fell down the hole. He cried for help, hoping to be heard by passers-by. But due to the loud thundering and noise of the heavy rain, no one could hear him. Cookie barked loudly and anxiously, circling around the hole.

Cookie suddenly ran quickly in the direction of home.

David’s mom anxiously looked towards the hole and saw him trapped into it.
