Paul Ford, writing for The Message, part of Medium:
She was surprised to see the stubborn power of politeness over time. Over time. That’s the thing. Mostly we talk about politeness in the moment. Please, thank you, no go ahead, I like your hat, cool shoes, you look nice today, please take my seat, sir, ma’am, etc. All good, but fleeting.
Enough to make me want to be polite!
