Just read an interesting thread in Mumsnet about attitudes to having TV on all day.
I tend to only put it on when Im watching something specific. Or if its already on I mute the sound until Im ready to watch again. I do have (loudish) music on most of the day and when Im working at the computer. It helps to blot out background noise which I find distracting. I can quite happily dis-attend the music because its under my control.
When we were kids and we first got a TV it was only put on in the evening. If a visitor arrived my mother immediately turned it off, or turned the sound down. Too bad if it was something I was watching. She believed it was very rude to have the TV on when visitors arrived (even if they were unexpected) as you were not paying due attention to them.
Have you ever been to see a Spiritualist
