When Lilacs Last in the Dooryard Bloom'd

To be honest, I didn't completely understand this whole poem. It was kinda confusing in most parts, I didn't know what the author was trying to say or anything. But I did catch a few phrases that got my attention. It said, "I saw battle-corpses, myriads of them, and the white skeletons of young men, I saw them, I saw the debris and debris of all the slain soldiers of the war, But I say they were not as was thought, they themselves were fully at rest, they suffer'd not, the living remain'd and suffer'd, the mother suffer'd, and the wife and the child and the musing comrade suffer'd, and the armies that remain'd suffer'd." I would agree with what he said about "they suffer'd not" only if every person he talked about went to heaven. But who knows. If some went to hell, I'm sure they'd be suffering a whole bunch. But in heaven they would of course be rejoicing! But anyways I would like to point about what he said about all of the family, or the living, was suffering. I don't really have much to say about this except that it's true. This poem kinda made me sad. And going to the cemetery was pretty intense too. And now that I'm thinking about it, just seeing all of those tombstones made me think about how short of a time we have here on earth. It made me value my life and I don't want to waste it. And I also thought about that WHEN I'm in heaven, I wouldn't want my family to be depressed that I'm gone. And I'm sure that when someone I know dies, they'll be thinking the same thing. So I'm not saying I'll be rejoicing when they die or anything, it just made me realize some things I guess.
