Some years ago, I broke my elbow, very badly. I sat for nearly three hours in the emergency room with an unsplinted fracture, waiting for somebody to do something about it, and hurting like hell.
When I finally got it X rayed, I told the technician I was likely to swear, as I was in a LOT of pain.
She said swearing was fine, as long as I didn't bite her. She said several patients, adult patients! had bitten her.
I went through the Xrays without one cussword. At the end, I smmiled sweetly, and told the technician I hoped all her children grew up to vote Republican. She said she wished I'd bitten her.
