The irony is that Bemis was always wishing that there was no one to hinder him from reading.
Explanation:
Henry Bemis is an avid reader, but besides not having much time to read, he is interrupted all the time which hinders his reading. He hates this and has a strong desire to be alone and with plenty of time to read in peace. The ironic is his wish happens and an H-bomb hits his city killing all the inhabitants, except him who was protected by the building where he was.
when he finds himself alone in the world, Henry Bemis is desperate and tries to find a way to die.
