Preaching professor Tom Long...
Preaching professor Tom Long tells a story about shopping in a grocery store one day. He was not in the best mood because he didn't enjoy grocery shopping. Then he ran into a mother and her son who really seemed to be enjoying their shopping. They made a game of it. She would read the first item on her list and then the little boy would race around the store until he found the item. They laughed and had a great time. Long met the mother and boy several times as he continued his shopping. Gradually, Long realized the little boy had a mental disability.
