“Forgiveness is the sweetest revenge.” I saw this wonderful old saying again in a book recently. It got me thinking about all the times that I have been    31   to forgive others in my life and all the joy that it has brought me. One    32   stands out particularly well.
I was a young boy at a summer camp. I was having a great time and    33___ everything about it except for another young boy of my age. To say we didn’t
   34   would be a statement that made the situation less serious than it really was. We spent most of the week irritating, insulting (侮辱), and picking on each other.
   35   finally came to a fight on the next to last day of camp. We got into a fist fight which I lost.    36   older boys broke it up before I was hurt too much. I spent the rest of the day alone, refusing to speak andlost in my own    37  .
The next day my spirits were    38   when Mom brought the boys in our cabin some of her delicious homemade    39  . I was enjoying a few slices of it when I saw the other boy sitting by himself at the bottom of the steps outside. He seemed very    40   right then. I am not sure what moved me to do so, but I took my pizza down and    41   it with him. It made all the anger and pain inside me    42  . We became friends after that. I never got into another fist fight either. I had found out that sharing and forgiving were much more fun and a lot less painful.
Forgiveness is    43   the sweetest revenge. It can turn an enemy into a friend. It can    44   a heart from the chains of anger, hatred, and pain. It can open a soul to the sweetness of love and joy once again. May your life always be    45   of sweet forgiveness.
