We use dates on a calendar to mark not only the passage of time day to day, but also to mark the progress of our lives. Think anniversaries, birthdays, or holidays. Today might even be important in that regard, and if so, how has your life changed since the last time this date came up? This week's feature at Paducah's Maiden Alley, One Day, uses this idea as its premise, telling one couple's story as they come together or drift apart over the course of their relationship.
