Hubby made that sign to me as they wheeled him into the OR. One of the nurses/docs/whatever in the preop area thought he was throwing up heavy metal horns and started laughing. Yeah, not really dude. Though we find.his misinterpretation funny now.
Side note, we were prepared to sign while he was on the vent in ICU. His hands were tied down the entire time he was.on it so we never used any signs. I talked. He gently nodded. That's it.
