Most sites are pseudo-conversational. That is, it APPEARS they are waiting for you to respond, but they arent, really. Its like you go back to the end of the Dept of Motor Vehicles line every time you hit the Enter key. They just keep track of what you were doing. Like they know whats in your cart, etc. You "are" your screen, but the site can hide a lot of data on your screen. Some of the data is hilited, some of the data is invisible, but its all there.
