Plato's "Phaedo" takes place during the last few hours of Socrates' life, and is largely a discussion on the immortality of the soul. This may or may not be relevant to your interests… Socrates technically committed suicide by drinking poison, but he was forced to do so by the Athens authorities. Less "catching the bus" and more "being forced into a suitcase and stuffed into the bus's baggage compartment whether you like it or not."
Still, many, many bus-chasers have spent their final hours reading "Phaedo," taking comfort in Socrates' words about spiritual immortality, his weirdly-chill attitude about his impending death, or both.
