Indeed, I didn't say subtle because I thought it was so obvious it went without saying. My bad.

Now why these social cues are so often subtle or ambiguous is itself an interesting question. It's not one I have any good answers to though. In this area, as in most, I'm a phenomenologist and not a theorist. Needless to say the phenomenology I've developed precludes telling a woman I'm interested in about the phenomenology I've developed. Except of course when I think she might find it attractive. Human social interactions are marvelously complex. Frankly my inclination to start navel gazing has set me back once or twice.
