I'm a post op nurse. She was absolutely not flirting. Sinus surgery can sometimes cause balance issues (due to sinuses connections to the ears) or if you change positions too quickly it can leave you seeing stars. That plus anesthesia means I don't trust you to get changed on your own. Unless you have been up and moving prior to getting dress (like walking to and from the bathroom), no one gets dressed in a room alone under my watch. Either family helps or I do if family isn't there. Too much paperwork if you fall.

I can almost guarantee she ran back and immediately washed her hands for about 8 minutes after you kissed her hand. I certainly would.
