It particularly drives me insane. I've known people of that age to act super worried if they go somewhere and there's not a TV they can have on. My ex would call it 'background noise' which is exactly what I don't want... annoying and repetitive commercials, concerning and distracting news broadcasts, fictional people engaged in trauma - why not some music? or silence? I've also wondered, what's the psychology of having dialogue playing on a loudspeaker all day and just tuning it out? I pointed out to her that no wonder she seemed to have a hard time listening to me in conversation when she has trained herself to hear people talking all day and not pay any attention to what they're saying. Leaving TVs on when nobody is watching them seems really improper to me too.
