    Clara Daly was seated on the flight to Beijing when an air hostess spoke over the loudspeaker: “Does anyone on board know sign language?”

Clara, 15, pressed the call button. The air hostess came by and explained the situation. A passenger, who was blind and deaf, seemed to want something, but he was traveling alone and the air hostess couldn’t understand what he needed.

Clara had been studying sign language for the past year and knew she’d be able to finger spell into the man’s palm（手掌）. So she walked toward the front of the plane, and knelt by the seat of Tim Cook. Gently taking his hand, she signed, “How are you? Are you OK?” Cook asked for some water. When it arrived, Clara returned to her seat. She came by again a bit later because he wanted to know the time. On her third visit, she stopped and stayed for a while.

“He doesn’t need anything. H e is lonely and wants to talk.” Clara said. So for the next hour, that was what they did. She talked about her family and her plans for the future. Even though Cook couldn’t see her, Clara looked attentively at his face with kindness. Cook told Clara how he had gradually become blind over time and shared stories of his days as a traveling salesman. He said he was very excited to have someone he could speak to and that it was the best trip he’d ever had.

All the passengers on board said that Clara was an angel（天使）.
