You have probably seen people sitting in front of their computers with headphones on, staring at a screen with a picture of an interesting document or an interesting website. And you have also seen people sitting in front of their computers with their fingers hovering over the keys, looking at the same screen, and writing down the stuff that is on the screen. It is a very common scenario and the problem is that the document that they are looking at is often the same document that they will later share with you.

And it is the same with your computer.
