Elegy in Elegy for My father, who is not dead

In strict terms, this poem isn't really an elegy. Technically, it has to be for someone who has died, but the speaker almost considers his father dead so it is close enough. Also, it isn't really a poem of mourning either but Hudgins calls it one. This speaker and his father have two opposing views on death. The father accepts that his time has come and "his reservations have been made". But, the son sees death not as a reunion with his father rather he doesn't want to die. I think his opinion is one that is driven out of youth. He is obviously relatively young, at least not old, if his father is alive and feels he has life to live and things to achieve. But, his father has done what he needs and knows his time has come. He's not as sure as his dad that he will ever see his father again, which makes him uneasy.
