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.

done just the right thing.
