Wood floors. I want to know how they know that. We are getting our floors fixed and now sanded and stained. A mere $5K. But I have done zero research on it with this computer, I let my wife handle it.

Are they looking at my computer search history or, forgive my lack of knowledge on the internet system, the router?

If it's the latter, then searching for cheerleader pics will make for some interesting ads on her computer... Actually, you should see her facebook. They've got prying and tracking your stuff to a science over there.
