This post caught my attention. I'm a dental hygienist. In our office, if a person is interested in a patient or vice-versa, the best way to find out if the person is single and available is through the receptionist. All the people in a dental office are pretty close to each other, or will know some pertinent details about each person. And no, we don't act nice to everyone, just the ones we want to be nice to.
So, my advice is: call the receptionist, don't wait until your next dental appointment! She might be single now, but this might change by the next visit.
I like the theme song idea. I'll have to think some more about that one...
