I remember sitting at an airport one day, waiting for my flight. I was1because I had a first-class ticket. And in first class, the seats are2, and the food is more delicious. Actually, I had the best seat on the whole plane: Seat 1A . Before boarding, I3a young lady who had a big suitcase(手提箱) and several carry-on bags holding a crying baby.4, the handle(把手) of her suitcase broke and the suitcase fell to the floor. She tried5the case and her bags landed on the floor, too. "Let me help." I said to her. I pulled her suitcase over my left shoulder, put her bags 6my right and asked, "Where to?" "Gate 20," she said, and showed me her ticket. Seat 24B. "Oh, we are on the same flight."

    Boarding started, and I7that she needed the first class ticket. "It looks like you could use the first-class ticket more than me. I know how8it can be flying with a kid. Why don't exchange tickets?"
    "Are you sure?" she asked. "Yes, just take my ticket and give me yours. I really don't9. I'm just going to be working the whole time, anyway." "That's very kind of you." she said, and expressed her10as we exchanged our tickets.

    Then we boarded the plane. I was surprised at the good11it gave me while watching her sit down in seat 1A. In fact, seat 24 B or12I was sitting didn't seem that bad at all. At one point during the flight I wanted to see how she was doing. So I13, walked to the first-class section and had a look. There she was with her baby, 14asleep. Seeing they were sleeping in big and15seat 1A. I felt like getting a million dollars. I've got to keep doing this kind of thing.
