| Even though it was only October, my students were already whispering about Christmas plans. With each passing day everyone became more 1 waiting for the final school bell. Upon its 2 everyone would run for their coats and go home, everyone except David. David was a small boy in ragged clothes. I had often 3 what kind of home life David had, and what kind of mother could send her son to school dressed so 4 for the cold winter months, without a coat, boots, or gloves. But something made David 5 . I can still remember he was always 6 a smile and willing to help. He always 7 after school to straighten chairs and mop the floor. We never talked much. He 8 just smile and ask what else he could do, then thank me for letting him stay and slowly 9 home. Weeks passed and the 10 ovre the coming Christmas grew into restlessness until the last day of 11 before the holiday break. I smiled in 12 as the last of them hurried out the door. Turning around I saw David 13 standing by my desk. "I have something for you" he said 14 from behind his back a small box. 15 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 16 saw nothing. I looked at David's smiling face and back into the box and said. "The box is nice, David, but it's 17 " "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 18 I looked at the proud dirty face that I had rarely given 19 to. After that Christmas, David and I became good friends and I never forgot the meaning 20 the little empty box set on my desk. | ||||
