Grave Secret

While awaiting a recent flight home.  Standing in line at airport security, after snaking back and forth between the numerous banded posts.  Noticing three men wind their way towards me.  Two in their late eighties, along with one of middle age.  Overhearing snippets of their conversation, as they pass by.  Learning two are father and son. Gleaning all three to be churchgoers.  The younger one mentioning how wonderful it is that he lives so close to his place of worship.  They then moving away from me, along the length of the line, only to return again. This time, in a grave voice, one of the older men revealing, "I kept it a secret until he died."  Arriving at the front of the line, I get waved up to place personal items on the conveyor belt.  Leaving the men behind, my mind does somersaults.  Who was it?  What was their relationship?  Was it church related?  Why did he feel it needed to be kept secret?  Were there unintended consequences?  What price did he pay?  I will never know the circumstances of this particular situation. My heart hoping he is at peace with it now.
