The Pecan Thief
When I was six years old, I was visiting my grandfather's farm in Kansas. Grandpa had sent me into the   36  to gather pecans for us to enjoy later.
Pecan picking was really   37  work and my little basket was only half full. I wasn't about to   38  Grandpa down. Just then something caught my   39  . A large brown squirrel was a few feet away.  I watched as he picked up a pecan, hurried to a tree and   40  in a large hole in the trunk. A moment later the squirrel   41  out and climbed down to the ground to pick up another nut. Once again, he took the pecan back to his hiding place.
Not so   42  anymore, I thought. I dashed over to the tree and looked into the hole. It was   43  with pecans! Golden pecans were right there for taking. This was my   44 . Handful by handful, I scooped all of those pecans into my basket. Now it was full! I was so   45  of myself. I couldn't wait to show Grandpa all the pecans.   46 , I ran back and shouted, “Look at all the pecans!” He looked into the basket and said, “Well, well, how did you find so many ? ” I told him how I'd   47  the squirrel and taken the pecans from his hiding place.
Grandpa congratulated me on how smart I'd been in observing the squirrel and his habits. Then he did something that   48  me. He handed the basket back to me and put his arm gently   49  my shoulders.
“That squirrel worked very hard to gather his winter   50  of food, ” he said. “Now that all of his pecans are gone, don't you think that little squirrel will   51  the cold winter? ”
“I didn't think about that,” I said.
“I know, ” Grandpa said. “But a good man should never take   52  of someone else's hard work.”
Suddenly I felt a bit   53 . The image of the starving squirrel wouldn't   54  my mind. There was only one thing I could do. I carried the basket back to the tree and poured all the nuts into the hole.
I didn't eat any pecans that night, but I had something much more filling—the   55  of knowing I had done just the right thing.
