D.L. Moody had a keen memory for names and faces. If one of his children was missing from Sunday school, he knew it, and he would do everything possible to find out why. One day he saw an absentee coming down the street, so he took off after her. She ran down the sidewalk, across the street, and through an alley into a saloon, up the stairs to a back apartment, into the bedroom, and then dived under the bed. Moody went after her, and just as he was claiming his prize, the mother showed up.
Panting from the exertion, Moody simply explained, "I'm Moody," He said that he had missed the girl and would be happy if all the family could come to the services. Within a few weeks he had every child in the family in his school.
