Someone quoted this in a comment on Chayyei Sarah's blog and I thought it was beautiful enough to repost here.
"They shall grow not old, as we that are left grow old:I find World War I elegies for fallen soldiers to be particularly beautiful and strikingly sad. (I first discovered them when I took a class on the history of World War I in college.)
Age shall not weary them, nor the years condemn.
At the going down of the sun and in the morning
We will remember them."
--Laurence Binyon, ""For the Fallen," September 1914
