"The day after tomorrow, this will all be over." Such a fucking cliche.

The thing that he seems to miss is the continuity of events which develops out of the dynamic relationship between what we do and otherwise experience, and the way we see our fundamental world. Tommy has a much simpler perspective on things, and sees his life, and time itself, as a linear storybook. Of course, this only creates conflict between us when I am in one of my particularly professorial moods, and apparently this is one of them.
Indeed, we are all rapidly approaching the very date when our "immortal souls" will be jettisoned into the flat, flat universe, and the only reason to care about this is that tomorrow, my miserable, monotonous piece of shit of a job won't be so sad.
