They were at least in their seventies. The wife was looking at paperback novels, when her husband spotted a chair near the window.
“I think I’m going to go sit down. I can hold the books you’ve picked out while you keep looking if you’d like.”
“Are you sure?”
“Yes,” he assured, and took a seat in the chair opening his arms so she could fill them with the dozen or so Agatha Christie books she had already picked out.
She laughed. “You know, I really have enough here. I don’t need any more.”
He looked at her and smiled. “You go ahead and get as many as you want.”
She accepted that with a nod and a smile and went back to the shelves, but just for a second.
She came back to him and started to thumb through the book spines, giggling. “I can’t remember what I already got.” He smiled and repositioned the stacks so she could see more easily.
She returned to her search and, in just a few minutes, came back to him and said, “I think I’m through looking. I really do have all I need.”
“Are you sure?” he asked.
She smiled at him, and said she was. They went to the cashier, walking side by side, him carrying her books for her.
