One afternoon, my son Adam asked me, “Are all people the same even if they are different in color?”

At grocery store, we 24 some apples --- red, green and yellow ones. Back home, I told Adam, “It’s time to 25 your question.” I put one apple of each 26 on the table. Then I looked at Adam, who had a 27 look on his face. 

“People are like apples. They come in all 28 colors, shapes and sizes. On the 29,  some of the apples may not 30 look as the others. ” As I was talking, Adam was 31 each one carefully. 

Then, I took each of the apples and peeled（削皮）them, 32 them back on the table, but 33 a different place. 

“Okay, Adam, tell me which is which.”

He said, “I 34 tell. They all look same now. ” “Take a bite of 35. See if that helps you 36 which one is which. ”

He took 37, and then a huge smile came across his face. . ”People are 38 like apples! They are all different, but once you 39 the outside, they’re pretty much the same on the inside. ”

He totally 40 it. I didn’t need to say or do anything else.
