A young girl was visiting her grandmother when she noticed that she was moving several duck figurines from the bottom shelf to the middle shelf of a cabinet.
The grandmother picked up another duck figurine from the bottom shelf and set it beside the first duck. She continued moving the ducks from one shelf to the next.
Finally, she stood back and looked at the cabinet.
“Hmm…” She moved back to the cabinet and began moving the ducks onto the top shelf.
“Grandma,” the little girl finally spoke, “what are you doing?”
“I’m just trying to get my ducks in a row,” the grandmother answered.
