I am NOT Prince Hamlet

The structure of this poem is of his thoughts or even bunny trails that some how always come together as he finishes his thought. When he observes the fog it is as if he is talking about him self because a little later it is some what the same. When he talks about the mermaids it is like the woman of his time, they talk to one another but not him. His theme, to me, is the changing of the ages and how he is alone and old in the end. He feels as if he is going crazy because he think he knows something great but people are changing. He feels like he is letting go and is now only in a spiral downward.
