One afternoon, my son Adam asked me, "Are all people the same even if they are different in color " I thought for a minute, and then I said, "I’ll explain, 1 you can just wait until we make a quick stop at the grocery store. I have something 2 to show you. "
At grocery store, we bought some apples-red, green and yellow ones. Back home, I told Adam, "It’s time to 3 your question." I put one apple of each type on the table. Then I looked at Adam, who had a 4 look on his face.
"People are like apples. They come in all different colors, shapes and sizes. On the 5 , some of the apples may not even look as the others. " As I was talking, Adam was 6 each one carefully. Then, I took each of the apples and peeled them, placing them back on the table, but 7 a different place.
"Okay, Adam, tell me which is which." He said, "I can’t tell. They all look same now." "Take a bite of 8 . See if that helps you decide which one is which. "
He took 9 , and then a huge smile came cross his face. "People are just like apples! They are all different, but once you 10 the outside, they’re pretty much the same on the inside. "
He totally got it. I didn’t need to say or do anything else.
