What is the last memory Mr. Meecham has of his wife?

Mr. Meecham's last memory;

"It was on a Saturday and they were getting ready to go to town. He was in a hurry to get to a cattle sale and she kept dragging around. Trying to decide this dress, that dress, something. I just don't know which one to wear.

Well, you best be for wearin one of them, Meecham said. I'm goin out to the truck and if you're not there in five minutes I'm gone and you'll have the rest of the day to make up your mind.

He had laid his pocket watch in the seat beside him and when five minutes were gone he cranked the truck. He saw her hand pull aside the kitchen curtain, her face lean palely to the glass. Then he drove away."
