Cody was an outgoing black dog with a big tail. Our dog Tasha was a similar spirit.     she shared the yard with Cody, they soon became fast friends.

We often saw a ball of black and white fur as they     neck and neck toward some unlucky bird that had just landed in the yard. The only time I saw any    between them was when we fed Tasha. Cody would jump up,     to share. However, Tasha would bare her teeth and shout     . Finally, Cody would slip away with his tail between her legs.

One day my husband came home quite     . He had just found Cody     by the side of the road, killed by a speeding truck. Tasha cleaned Cody’s smooth     fur with her nose and mouth and whined(哀鸣). Over the next few weeks, Tasha was in low     with her tail between her legs. She     missed her old friend.

At the same time, Tasha’s food dish disappeared. We replaced it with another,     to have that one disappear as well. There     bowls, plates, even an old coffee can. They all disappeared. Finally, the     was solved when our neighbor knocked on our door, her arms loaded with the missing dishes, some still half-full of dog   .

“Are these yours?” she asked. “I saw Tasha headed toward the     , so I followed her. Then I noticed all these dishes in a pile.”

      , I asked, “Where were they?”

“It was right by the place where Cody     .”

Could Tasha have been begging her old friend back by offering him the one thing she       to give him when he was alive?

Even today,     the story makes me feel sad. It       me that I need to share whatever blessings I’ve received with others — before it’s too late.
