Smiles and tears are part of life. But do you find enough time for smiling? I’m not asking if you experience lots of good times. Of course, we should smile during the happy times. But do you also smile during the difficult times.

Erma Bombeck is famous for her funny books. But she wrote one about a more serious subject –cancer in children. The book is titled, I WANT TO GROW HAIR,ＩWANT TO GROW UP. Erma talks with many children who have cancer and learns important lessons from them. She learns, for example, that cancer survivors know how they should smile at life, though they are receiving chemotherapy.

She tells about the experience of 15-year-old Jessica. Jessica’s leg was cut off at the knee because of cancer. She was learning to wear a prosthesis(假肢). Jessica told about playing soccer. She hit the ball hard with her foot. The ball flew off in one direction while her man-made leg flew another way. Then the brave girl lay on the floor, laughing happily.

As the saying goes, “There’s a time to cry and a time to laugh.” Do you find plenty of time to laugh.

You can smile if you find reasons to smile during the difficult times. Only survivors know how to smile. If you can smile even when you’re in trouble, you will make it. Remember to smile and the whole world will smile with you.
