Last week, I got the strangest email, and I still can’t quite figure out what to make of it.

N, from the Natural Sciences department at Bentley University, found a sealed NetFlix DVD on a cart in one of the buildings there. She also noticed the corresponding torn-off part of the envelope, the part with the subscriber’s address, in a nearby wastepaper basket. And the address (she said) was mine. So she looked me up on Google and emailed me, asking if I wanted her to drop the DVD in a mailbox.

But I don’t go to Bentley, have not been to Bentley; and that certainly isn’t my DVD.
