Query: I haven't honked my car horn since this book came out

Upon reading Tom Brokaw's books, I was inspired to signal even while getting into the turn lane with no one behind me. But that was nowhere near the level of inspiration this book has given me to live a better life.Therefore, effective immediately I will heed Li'l Russ's example and stop honking my car horn. If there is a safety hazard or I become impatient, I'll just yell out the window. Everything changed on 9/11.
