Thomas Morris worked for nearly 30 years at the Brentwood Post Office in Washington, D.C.
"When he would get off work, he would get home in the early morning and we would go out to eat breakfast at 2, 3, 4 o'clock in the morning," his wife, Mary, says.
The couple married on May 1, 1991, within 90 days of meeting each other at his mother's funeral. Mary says she was impressed by how well he had looked after his mother.
"And you know if a man treats his mother right, he's going to treat his wife right," she explains during a visit to StoryCorps in Beach Park, Ill.
