One friend called another on the phone.
When the latter answered, the former (after sufficiently identifying himself) replied: “Hey, got your wedding invite. I’m supposed to respond with any ‘known regrets,’ it says. What about unknown regrets, though? Who do I talk to about any possible unknown regrets?”
“I see,” said the second friend. “Unfortunately, I’m not in a position to help you. We’re currently only equipped to deal with known regrets here. We looked into possibly doing work with unknown regrets, but that’s a whole big thing. Lot of moving parts with unknown regrets.”
They didn’t call it a bit. Like, they didn’t use that word. But it was pretty obviously a bit.
