Even though it was only October, my students were already whispering about Christmas plans. With each passing day everyone became more  31   waiting for the final school bell. Upon its   32  everyone would run for their coats and go home, everyone except David
David was a small boy in ragged clothes. I had often  33  what kind of home life David had, and what kind of mother could send her son to school dressed so 34  for the cold winter months, without a coat, boots, or gloves. But something made David   35  . I can still remember he was always  36  a smile and willing to help. He always  37  after school to straighten chairs and mop the floor. We never talked much. He  38  just smile and ask what else he could do ,then thank me for letting him stay and slowly  39  home.
Weeks passed and the  40  over the coming Christmas grew into restlessness until the last day of  41  before the holiday break. I smiled in  42  as the last of them hurried out the door. Turning around I saw David 43  standing by my desk.  
“I have something for you” he said and   44  from behind his back a small box.  45    it to me, he said anxiously, “Open it. ”I took the box from him, thanked him and slowly unwrapped it. I lifted the lid and to my 46  saw nothing. I looked at David’s smiling face and back into the box and said. “The box is nice, David, but it’ s  47 . ”
“ Oh no it isn’t ,” said David “ It’s full of love, my mum told me before she died that love was something you couldn’t see or touch unless you know it’s there .”
Tears filled my eyes  48  Ilooked at the proud dirty face that I had rarely given  49   to. After that Christmas, David and I became good friends and I never forgot the meaning 50  the little empty box set on my desk.
