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 simply 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  I saw nothing. I looked at David‘s smiling face add 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  I looked 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.

If you see someone drowning, speed is very important. Once you get him out of the water, if he isn't breathing, you have four minutes before his brain is completely destroyed. Support his neck, move his head back and press his chin upwards. This stops the tongue blocking the airway in the throat and is sometimes enough to get him breathing again. If that doesn't work, start mouth-to-mouth breathing. Press his nostrils (the two holes at the end of your nose, through which you breathe and smell things) together with your fingers. Open your mouth and take a deep breath. Blow into his lungs until his chest rises, then remove your mouth and watch his chest fall. Repeat twelve times a minute. Keep doing until professional help arrives.

    To bring a child back to life, keep your lips around his mouth and gently blow into his mouth. Give the first four breaths as quickly as possible to fill the blood with oxygen. If, in spite of your efforts, he starts turning a blue-grey colour, and you can feel no pulse, then pressing is the last chance of saving his life.

    With arms straight, rock forwards, pressing down on the lower half of the breastbone. Don't be too hard or you may break a rib. Check how effective you are by seeing if his colour improves or his pulse becomes independent to your chest pressing. If this happens, stop the pressing. Otherwise continue until rescue arrives.
