Working in the healthcare field (both my wife and I, over 20 years each) we know that it is a workplace that puts both sexes together in order to get the job done. We also know, understand and accept that physical, even mental attraction is a fact of life. You can't prevent an attraction, you can decide how you are going to respond or react to it. Looking is just looking. Talking is just talking. Even flirting (to a certain degree) is a way of saying "I not only notice you, but I am letting you know that my mind isn't sitting here idly either". Verbal interaction, clever comebacks, double entendre and the like are a way of showing other people that you recognize, value, trust, appreciate and actually LIKE spending time working with them. I've looked, I've shamelessly flirted, I've never touched, never unbuttoned or unzipped, and no bodily fluids ever came into play. My wife knows this, trusts me, and I trust her. The one thing of attraction that I've not mentioned, and it is the trickiest of all, is emotional. That is a banana peel on an icy sidewalk with a strong wind blowing and you're wearing smooth soled shoes. Flirting (for me) is always kept to the verbal, visual and intellectual level. If there is ever a sign that someone's "feeling it"? Then it's time for a chat to clarify and apologize that I didn't realize it was being taken in that way.
