The end of the world and i'm the only person left

I walked to the train station, and when i got there took out my book. Its a big book, a hulking tome. The platform was evenly populated, and more people were joining.

Then they were gone. I was the worlds last human. The sole homo sapian in a post nuclear world full of cockroaches and rhinos (and maybe even wombats).

Then i looked up and saw that my train was fading into the distance.

I was only marginally late for work, and noone really noticed.
