We went in 8th grade. My 7th and 8th grade History teacher was a HUGE Civil War buff and even took part in several reenactments. Our trip happened to fall on a rainy day when we went to Arlington. Everybody was griping and complaining about the rain until all of the sudden, Mr Jones said, "It's raining on all of us equally, but there is one person who is not complaining. (meaning the soldier on guard who was getting pelted by rain) Let's honor him and his fallen brothers by also not complaining."
There wasn't a sound after that.
