| Recently, my husband and I had the opportunity to do something good for two people who were complete stranger to us. It made us feel so good to be able to do it that I thought I should 1 . We were traveling down to Mexico for Thanksgiving week with our family. 2 we sat in the 3 first two seats in the first row of first class waiting for the plane to take off. I 4 heard one of the flight attendants (乘务员) telling 5 that there was a couple sitting in the 6 of the plane who had just been married the previous day and were on their 7 . They had 8 their flight eight months in 9 but, owing to some schedule changes, had not been able to get 10 together, and no one else on the plane was 11 to move and the bride was in 12 . I turned to my husband and told him what I heard. We 13 agreed and I called the flight attendant 14 to tell her that we'd be happy to give up our seats to this couple. The flight attendant seemed amazed and said "Really? Are you sure?" We said "Absolutely!" So, we 15 to the back of the plane in separate seats. The flight attendants were extremely 16 and took good care of us even though we were no longer sitting in first 17 , and we both made friends with the people sitting around us, who, as it 18 didn't know why the young woman was crying or that they were newly married, and had a great flight. I had to go back to the front of the plane to 19 up a forgotten item at one point during the flight and 20 that the couple were sitting very close together, happily enjoying champagne. It really made my day and Thanksgiving week get off to such a wonderful start! | ||||
