FOX Nation host Abby Hornacek takes a closer look at the topics and buzz words you find your friends and coworkers using to sound intelligent. Each week Abby and her expert guests will tackle topics we take for granted and help to explain the roots and meanings behind them.

This week, Geoffrey Wawro, Professor of Military History and Director of the Military History Center at the University of North Texas, joins Abby in the classroom to help with her lesson plan. Geoffrey explains the importance of Memorial Day, how it began, and how Americans can continue to honor this important day.
