Weeks passed and the ___30_____over the coming Christmas grew into restlessness until the last day of ___31___before the holiday break. I smiled in ___32____as the last of them hurried out the door. Turning around I saw David ____33___standing by my desk. 
“I have something for you,” he said and ___34___ from behind his back a small box.  ____35___it to me, he said anxiously. “Open it.” I took the box from him, thanked him and slowly unwrapped it. I lift the lid and to my ___36___saw nothing. I looked at David’s smiling face and back into the box and said, “The box is nice, David, but it’s ___37____”.

Tears filled my eyes ___38___I looked at the proud dirty face that I had rarely given ____39___to. After that Christmas, David and I became good friends and I never forgot the meaning ____40___the little empty box set on my desk..
