I always thought the idea of pausing live tv was kinda silly.
Can I assume you are not yet married or have children???
My wife is notorious for this. She has nothing to say, until I sit down to watch something and as soon as she hits the Sofa and she sees whatever it is I wanted to watch (insert sporting event of choice), and automatically begins to talk uncontrollably. I found that just turning the volume up to compensate got me in trouble, however, the Pause works wonders. Same for children.........now if only they both came with a mute button.
