Yesterday my father-in-law took a taxi home. The taxi driver subsequently picked up another passenger, who found a bunch of keys - one of them apparently a car key - on the back seat. After dropping off that passenger, the driver took the trouble to go out of his way to drive back to our home to ask if the keys belonged to my father-in-law. As it happens, they didn't - presumably having been dropped by an earlier passenger - but in a time when Hong Kong is increasingly fractious and divided, it's good to be reminded that simple human acts of kindness can still be found here. And if you left your keys in a taxi yesterday, the driver will have handed them in to the police by now.
The heading, by the way, is from Shakespeare's A Merchant of Venice. Looking it up to be sure of getting the wording right, I learned that in Shakespeare's time "naughty" meant "worthless" (i.e. "worth naught"). So I should also thank the taxi driver for furthering my etymological education.
