This line in "The Great Gatsby" (as Nick Carraway's riding the train from Long Island into New York City) is a transitional fossil record:
"My commutation ticket came back to me with a dark stain from his hand."
Because the modern verb "commuting" and nouns "commuter" and "commute"....
stem from names for multi-ride railroad/streetcar passes that truncated or "commuted" fare payments ("commute" here being the same verb we use in "commuted their original prison sentence").
New blog post about "The Great Gatsby", Nick Carraway's struggle to love, multiple new stage adaptations, what's hard about porting a story to another medium, anti-racism tradeoffs, and @jacob being a patient friend
