Example Sentences

• "Two days have passed since that day of lunacy. What a noise and a fuss and a chattering and an uproar there was! And what a welter of unseemliness and disorder and stupidity and bad manners! And I the cause of it all! Yet part of the scene was also ridiculous—at all events to myself it was so."
