As a typical nerd I suffer from the shy guy rule of inverse talkage:

The more attractive I find a woman, the more befuddled my brain becomes in their presence, and as a result, the less able I am to construct coherent sentences when around them. So, if a woman speaks to me, and I respond with a simple grunt or strange stare, I am actually paying them an unintentional compliment of the highest sort. I suspect that most women understand this already to a degree.

If I actually start talking though, I may engage in overbabble, which is really a side effect of the befuddlement. My rambling discourse about the nature of spoon varnish is actually a long hand way of saying, "Gee, you have really nice eyes."

So, now that we understand, let us summarize:

Very little talking = I am overwhelmed by a woman's attractiveness.

Too much talking = I am trying to avoid mentioning how great I think a woman's eyes are.

A normal amount of talking in a possibly eloquent manner = Being polite, but not actually interested.
