A large brown squirrel was a few feet away.I watched as he picked up a pecan, hurried to a tree and 5 in a large hole in the trunk.A moment later the squirrel 6 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 7 anymore, I thought.I dashed over to the tree and looked into the hole.It was 8 with pecans!Golden pecans were right there for taking.This was my 9 . Handful by handful, I scooped all of those pecans into my basket.Now it was full! I was so 10 of myself.I couldn' t wait to show Grandpa all the pecans. 11 , 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 12 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 13 me.He handed the basket back to me and put his arm gently 14 my shoulders. "That squirrel worked very hard to gather his winter 15 of food, " he said."Now that all of his pecans are gone, don' t you think that little squirrel will 16 the cold winter?" "I didn't think about that, " I said. "I know, " Grandpa said."But a good man should never take 17 of someone else' s hard work." Suddenly I felt a bit 18 .The image of the starving squirrel wouldn't 19 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.
