...any cemetery 

 One of the most beautiful ceremonies that I've ever been to was at Arlington for my uncle's father that had his remains recovered from Vietnam. There were jets flying overhead, we had a motorcade escort all through DC area, it was beautiful.

 I missed my uncle’s internment. This was my first opportunity to pay my respects. I’m glad your uncle’s father’s remains were able to be recovered from Vietnam. 

 How many people do you really think to reach who go to this cemetery?

You do know you're posting to people from Uzbekistan, Japan, Germany, France, canada, Korea, etc etc etc? 

 To be more productive in my comment: I would suggest you make the comment unspecific , e.g. "when visiting a cemetery...." 

 My comment was specific to Arlington National Cemetery which is also a popular tourist destination. Stopping and placing your hand over your heart as a civilian for a passing funeral procession is specific to that place. 

 Way to be an asshole. People from around the world were visiting fyi. 

 It's a slow day in Mom's basement, clearly.
