But if time exists only in my head, and I'm the last human being, it will end with my death. The thought cheers me. I may be in a position to murder time. The big net will tear and fall, with its sad contents, into oblivion. I'm owed some gratitude, but no one after my death will know I murdered time. Really these thoughts are quite meaningless. Things happen, and, like millions of people before me, I look for meaning in them, because my vanity will not allow me to admit that the whole meaning of an event lies in the event itself.
