One afternoon, Tim, my son, came home from school with a puzzled look on his face．I asked him what was the matter and he said, “Are all the people the same even though their skin colors are different?” I thought for a moment, then said, “I’ll explain．” I put apples of different colors on the table：first a red apple, then a green apple and at last a yellow apple．I looked at Tim．
“Tim, people are just like apples．They come in all different colors, shapes and sizes．See, some of the apples have been bumped(碰撞)and bruised(擦伤)．On the outside, they may not even look as delicious as the others．” As I was talking, Tim was checking each apple carefully．
Then, I took each of the apples and peeled them, putting them back on the table, but in a different place．
“OK, Tim, tell me which one is the red apple, the green apple and the yellow apple．”
Tim said, “I can’t．They all look the same now．”
“Now taste each of them．See if that helps you find out which one is which．”
Tim did so, and then a big smile came across his face．“People are just like apples! They are all different, but if you take off the outside, they’re quite the same inside．”
Now I see Tim has already understood me and I don’t need to say or do anything else．
From then on, when I help myself to an apple, it tastes a little sweeter than before．
What wonderful food for thought!
