"Don't shout as if my ears don't work "
===========
Too right. I was in a medical office recently, and the nurse spoke so loud that my arms shot straight up in the air in pain. She drew back, alarmed.

"Don't talk so loud," I said, "You're hurting me." She didn't apologize, but she started talking normally.

I believe she was the nurse who told my blood pressure was some number over 24. I decided not to worry about it.
