The boy had no hair on the side of his head but a set of blue spiked(成锥形的) hair on top of it. His nose was 2 , and a ring ran through the hole. A chain went across his face and it was connected to his earring. He held a skateboard under one arm and a basketball under the other.

Now I came face to face with the young man. I stepped aside and let him5. He replied very6, "Thank you very much."
On our way to the car, I 7 Cindy for holding open the door for the boy. To my surprise, she didn't seem to be troubled by the young boy's 8 . But I wanted to make sure. I wanted to be ready to talk about freedom of expressing themselves and allowing people's 9 .
As it turned out, the person 10needed the talk was me. The only thing Cindy noticed about the boy was the fact that his arms were 11 . "He held a skateboard under one arm and a basketball under the other. He would have a 12 time to open the door, " said Cindy.
I just paid attention to the partially shaved (部分剃光的)head, the set of spiked hair, the piercing and the chain. She saw a person carrying 13 under each arm and heading toward a(n) 14 door.
What my granddaughter said reminded me that I should change my ways of judging people and 15 my granddaughter to be open-minded and warm-hearted.
