It's true. I don't own one now, and never have

It's not the sort of thing that I make a point of announcing. But when someone repeatedly asks me if I've seen certain TV programs, I do disclose it.
People have a very interesting range of responses: annoyance, envy, contempt, admiration, disappointment. The one that puzzles me the most is defensiveness - some folks feel compelled to justify the existence of TV in their lives.
Here's my take on it: I don't like television, so I don't watch it. If you like it and watch it, it's none of my business.
Though I would be interested in knowing why you point out triumphantly, "But you DO have a computer at home!"
