One year ago Bertha and Grace became close friends at a college in Dartmouth.
One day， Bertha said that her aunt Margaret had invited（邀请） her to spend the summer holiday with her. And they would have picnics and parties as well. But Grace told Bertha that she planned to stay in Clarkman’s bookstore until the new term began.
Grace had to do something to feed herself because her parents died many years ago. Bertha  watched her friend’s  pale (苍白的) face. Just then she got a good idea. The next day when  Grace came back， Bertha showed her an invitation letter from her aunt Margaret.
“Grace， would you like to spend your holiday with us? I will help you find a part-time job in our town.” Grace cried after reading it.
“Grace， please spend the holiday with me， or Margaret will be disappointed (失望的). I want you to be happy，” Bertha said.
The holiday quickly passed by， and finally one letter from Margaret came to Bertha.
“Bertha， Grace is the sweetest girl in the world， and I am very grateful(感激的) to you for sending her here.”
