In the last 24 hours, I have observed:
--Cashier to customer: "Thank you, ma'am, I mean, sir." Customer to cashier: "No worries--either works!"
--Homeless man peeling off outer layer of Tartine croissant before enjoying the inside.
--My own daughter standing on our stoop yelling to the car parked in front of our house, "Don't block the driveway!" as they smiled and waved to her.
