LOL! There's plenty of other things to do in life besides watch TV. No need to explain yourelf. If you wanted to see something, there are many online avenues to watch a favorite show or a movie.
Probably the most important thing not having a TV does (I do watch some DVDs) is it causes you to view the world differently than everyone who watches and it is so fun to see things differently.
I am the same way with the smart phones. I recently read in the WSJ something to the effect that I have this device the puts all the world’s knowledge at my finger tips, I use it to look at videos of cats and to argue with strangers. An hour a day on the internet is my vice. That and chocolate milkshakes.
