When I was 9, we packed up our home in Los Angeles and arrived at Heathrow, London on a gray January morning. Everyone in the family settled quickly into the city except me. Without my beloved beaches and endless blue—sky days, I felt at a loss and out of place. Until I made a discovery.

Southbank, at an eastern bend in the Thames, is the center of British skateboarding, where the continuous crashing of skateboards left your head ringing .I loved it. I soon made friends with the local skaters. We spoke our own language. And my favorite: Safe. Safe meant cool. It meant hello. It meant don't worry about it. Once, when trying a certain trick on the beam (横杆), I fell onto the stones, damaging a nerve in my hand, and Toby came over, helping me up: Safe, man. Safe. A few minutes later, when I landed the trick, my friends beat their boards loud, shouting: “ Safe! Safe! Safe!” And that's what mattered — landing tricks, being a good skater.

When I was 15, my family moved to Washington. I tried skateboarding there, but the locals were far less welcoming. Within a couple of years, I'd given it up.

When I returned to London in 2004, I found myself wandering down to Southbank, spending hours there. I've traveled back several times since, most recently this past spring. The day was cold but clear: tourists and Londoners stopped to watch the skaters. Weaving (穿梭) among the kids who rushed by on their boards, I found my way to the beam. Then a rail — thin teenager, in a baggy white T — shirt, skidded (滑) up to the beam. He sat next to me. He seemed not to notice the man next to him. But soon I caught a few of his glances. “I was a local here 20 years ago,” I told him. Then, slowly, he began to nod his head. “Safe, man. Safe.”

“Yeah,” I said. “Safe.”

What can we learn about the author soon after he moved to London?

Love is one of life’s greatest motivators. That is exactly what inspired Zack to design a fully electric off-road wheelchair for his girlfriend suffering from paralysis (瘫痪).

Like most wheelchair-users, Cambry has always been restricted to the pavement for most of her adult life. Aside from that, using a wheelchair across long distances makes her shoulders ache. Zack Nelson, her boyfriend, wanted to give her the ability to explore more places conveniently, so he made a special wheelchair for her, which would make it possible.

Zack began by combining two electric bikes and installing a seat in the centre. It worked! Cambry experienced a whole new level of freedom using her new “ride”, and she couldn’t be more grateful to Zack for coming up with it. Fast forward to a year later, Cambry and Zack tied the knot. They also began mass-production of the special wheelchair. Throughout that time, they improved the original design to make it a more reliable off-roader.

While similar vehicles already exist in the market, they said they’re either slow or cost as much as a car. Cambry and Zack wanted to build something quick, light, super long-range, and affordable at the same time. However, coming up with that kind of electric off-roader wasn’t easy.

The toughest challenge when developing the special wheelchair is the price. “We wanted to create something that is affordable for everyone. Finding quality components, and a simple enough design at the cheapest price possibly took quite a bit of time,” said Zack. “But I think we have something now that everyone will be able to enjoy, at a fraction (少量) of the cost of other ‘off-road wheelchairs’ currently on the market.” Another great thing about the vehicle is that it’s silent. Its rider will have no difficulty chatting with their companion while using it. Cambry and Zack are very happy with the fully-electric machine, and they hope that other wheelchair-users will also benefit from it.

Lena could clearly remember the night she had to flee her home in Hungary. It was the beginning of the Second World War and her family needed to escape fast. She quickly packed a suitcase with a few pieces of clothing, her diary, and her most prized possession — a beautiful silk scarf. Lena and her best friend, Monika, had persuaded their parents to buy them matching scarves, which they each wore tied around their neck as a symbol of their friendship. Lena had no idea that when she left for America that night, she would never return. Her family settled on the sunny west coast in California.

Lena kept that special silk scarf for many years. One day she decided to give it to her granddaughter, Eliza, to wear to her first job interview for good luck. Lena was afraid that Eliza would lose the scarf, but her granddaughter reassured her, “Don’t worry, Grandma, nothing’s going to happen to your scarf. You’ll see. It is going to bring both of us luck today.” With that, Eliza kissed her grandmother on the cheek and left.

That afternoon, Eliza left the interview feeling confident that she had got the job. She decided to celebrate by going to a restaurant. As she sat at her table, she felt someone staring at her. Sitting next to her was an elderly woman who could not take her eyes off her. “I’m sorry. Do I know you?” Eliza asked.

“I’m sorry, dear, but you remind me of someone I once knew,” the old woman replied in an accented voice. “My best friend looked like you and used to wear a scarf just like the one you’re wearing around your neck.” Eliza felt goose bumps go up her arms. She had heard stories of her grandmother’s best friend and knew the significance of the scarf. Could this be Monika, her grandmother’s childhood friend?
