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.
