| 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 2 at the grocery store. I have something 3 to show you." At grocery store, we 4 some apples-red, green and yellow ones. Back home, I told Adam, "It's time to 5 your question." I put one apple of each 6 on the table. Then I looked at Adam, who had a 7 look on his face. "People are like apples. They come in all 8 colors, shapes and sizes. On the 9 , some of the apples may not 10 look as the others." As I was talking, Adam was 11 each one carefully. Then, I took each of the apples and peeled (削皮) them, 12 them back on the table, but 13 a different place. "Okay, Adam, tell me which is which." He said, "I 14 tell. They all look same now." "Take a bite of 15 . See if that helps you 16 which one is which." He took 17 , and then a huge smile came cross his face. "People are 18 like apples! They are all different, but once you 19 the outside, they're pretty much the same on the inside." He totally 20 it. I didn't need to say or do anything else. | ||||
