Mary was waiting for the airplane to take off.She was happy to have a seat by herself.Just then，an air hostess（空姐） came up to her and asked， "Would you mind changing your seat？" The girl behind Mary had a black﹣and﹣blue face and a sad expression.She had her arms broken，and she needed help. "I don't want to sit there." Mary thought immediately.But the soft voice came again， "She needs help." Finally，Mary moved to that seat.

The girl was named Emily.She had been in a car accident and now was on her way for treatment（治疗）.

When the snacks and juice arrived，Mary realized that Emily could not feed herself.Mary considered offering to feed her but hesitated（犹豫），as it seemed too impolite to offer service to a stranger.But then Mary realized that Emily's need was more important.Mary offered to help her eat.Although Emily was uncomfortable to accept，she agreed.They became closer and closer in a short time.By the end of the five﹣hour trip，Mary's heart had warmed，and the time was really better spent than if she had just sat by herself.

Mary was very glad that she had sat next to Emily and fed her.Love sometimes goes beyond human border（边界） and removes（消除） the fears that keep people away.When we reach our hands to serve another，we grow to live in a larger and more rewarding （有回报的） world.
