It would never EVER cross my mind to put the TV on when my children have friends over to play, unless they specifically ask to watch a certain film, and even then I would probably try and encourage them to do something else. But when my dd's go to other people's houses the TV always seems to be on - today me and the dd's went to a friend's house to have lunch and for the children to play together, and the mum put the TV on (some film) as soon as we sat down to eat - I just don't get that AT ALL!
