Which Service?

One Sunday morning, the priest saw little Paul staring up at the large plaque that hung in the church's foyer. The plaque was covered with names and small American flags were mounted on either side of it.

Little Paul asked, "Father Joseph, what is this? Father Joseph replied, "Well, son, it's a memorial to all the young men and women who died in the service." They stood together quietly, staring at the memorial plaque. Then little Paul asked, "Which service? Is it the 9:00 or the 10:30?"
