New York doesn't have "customs" — it has survival protocols. Master these, and you're not a tourist.
Brief. Eye contact. Nod or "Hey." Handshake in business; fist bump / "what's good" in neighborhoods. No air kisses unless you're actually European.
Subway at 8 AM: you're breathing your neighbor's air. Accept it. Don't lean on poles. Move to center. Backpack off — wear it front.
Look people in the eye when speaking. On street: brief glance = "I see you." Stare = challenge. Phone zombies = obstacles.
"On time" = 5 minutes early. "New York minute" = the interval between light green and horn honk. Don't waste it.
47% foreign-born. 800+ languages. Your bodega guy (Yemeni), nail tech (Nepali), surgeon (Indian), barista (Polish), landlord (Chinese). You navigate difference daily.
Met, MoMA, Whitney, Brooklyn Museum, Public Theater, BAM, Carnegie Hall, Blue Note, basement comedy, subway musicians. Culture is infrastructure.
Yankees/Mets, Knicks/Nets, Giants/Jets, Rangers/Islanders/Devils. Pick one per sport. Wear the hat. Talk trash. It's community.
Pizza (fold it), bagel (toasted, schmear), pastrami (Katz's), halal cart (white sauce + hot), dumplings (Flushing), roti (Richmond Hill), omakase (LES), pierogi (Greenpoint). Never eat the same cuisine twice in a week unless you're broke.
Sidewalk = highway. Right lane = slow. Left lane = pass. Stop = step aside. Don't block the flow.
Spanish, Chinese, Russian, Yiddish, Bengali, Arabic, Haitian Creole, Korean, Polish, French Creole — hear them all on one train car.
The City. The Big Apple. Gotham. The 212/718/917/347/929. "Upstate" = anything north of Westchester. "The Island" = Long Island. "Jersey" = NJ (said with affection or disdain).
Learn the rhythm. Then add your own beat.
