One evening in the year 97 AD, Roman lawyer Pliny the Younger found himself alone at his dinner table, a seat conspicuously empty. His friend Septicius Clarus, who had promised to join him for a night of food, wine, and conversation, had failed to appear. Pliny responded with a snub letter.

Rob Delaney joined us at the 10th anniversary Letters Live show at London's Royal Albert Hall to read Pliny's letter.
