Thanksgiving Day was near. The Grade 7 teacher asked her students to 16 a picture of something for which they were thankful. People celebrated the 17 with turkey and other traditional goods of the season. So, 18 of her students’ pictures were about them. However, Jack made a ___19____ kind of picture. Jack was not the same as other boys. He always looked sad. When asked to draw a picture of something for which he was 20 , he drew a hand. Other students were all very 21 in the picture. Whose hand could it be? One child guessed it was the hand of a farmer, because farmers feed 22 . Another suggested a police officer, because the police 23 and care for people. Still 24 guessed it was the hand of God, for God feeds us. And so the 25 went on until the teacher almost forgot the young artist himself. When the children had gone on to other subjects, she stopped at Jack’s desk and asked him 26 it was. The little boy looked up and said in a 27 voice, “It’s yours, teacher.” She remembered the times she had taken his hand and 28 with him here or there, as she had with the other students. She often said, “ 29 my hand, Jack. We’ll go outside.” Or, “Let me show you how to use your pencil.” Jack was most thankful for his ___30____ hand.
