This happens sometimes: Husband Guy and I will finish watching a DVD and the TV is still set to Video-4 or whichever one is pointing at the DVD machine. The screen is all dark and looks off. And the conversation goes like this:
Me: "The TV is still on."
Him: "No, it's not."
Me: "Yes, it is."
Him: "It's off, look at it."
Me: "I can still hear it. It's on."
Him: "No, you can't. It's. Already. Off." *huffily pick up the remote and push some buttons*
TV: *abruptly starts showing whatever was on the current channel*
Him: *sheepishly* "Oh..."
Me: *play-sneer* "I love you anyway."
XD Or I'll walk by and notice the TV still on, I turn it off, tell him that he forgot to turn the TV off and he said it looked off to him.
We knew a guy in highschool who said he could feel the vibes from across a small room. And that's the only other person I've ever met who could sense TVs being on.
