Twelve years ago yesterday, my mother gave birth to the most beautiful girl.  31 , we were later given the  32  that this little girl, who was three and a half months old, would only have 14 days on the earth. It’s hard to understand what kind of  33  you have when you find out that you’re  34 something that you don’t even know.

As time went on, the number of days kept growing, which gave us  35 . When the doctors said that we could take her home, that was  36 reality hit. We had no  37 .

I am from a small town with  38 hospitals, but when you don’t have money, you just don’t  have it. My mother tried for days to get the money, but nothing  39 each time. A caseworker(社会工作者) was even doing her best. It’s  40 that it almost felt as if we had to  41  a baby from the hospital.

One day the caseworker walked into her boss’s office to  42  again. As she walked out,  43 down yet again, out of nowhere a man walked up to her. He  44 her a handful of money and said, “Please give this to the lady in  45 , so she can take her daughter home.” She looked down at her hand with tears in her eyes. As she looked back up to thank him, he was  46  . They searched all over that hospital and he was no where to be  47 .

Thanks to the guy that I will  48 know, we could take home that  49 baby girl that was only given 14 days to live, and celebrated her 12th birthday yesterday. I am grateful to this man and feel that his act of  50 should be shared with everyone.
