I don't even answer the phone when I'm watching TV.
Seriously. Unless I know who it is, AND I WANT TO TALK TO THEM, I don't answer the phone.
I was having a group of people over one time in the back yard and the phone rang and I ignored it. My boss's wife said, "Aren't you going to answer it?"
I said, "no, I don't care who's calling, they can leave a message if it's important". She said, "Oh, I can't do that, I need to answer it"
I don't give a fuck who's calling. When you're on the phone all day at work, the last thing you want to do when you get home is answer the phone. It will just be someone who wants something that I probably don't want.
