Read the following excerpt from F. Scott Fitzgerald's The Great Gatsby:
I spent my Saturday nights in New York, because those gleaming, dazzling parties of his were with me so vividly that I could still hear the music and the laughter, faint and incessant, from his garden, and the cars going up and down his drive. One night I did hear a material car there, and saw its lights stop at his front steps. But I didn't investigate. Probably it was some final guest who had been away at the ends of the earth and didn't know that the party was over.
