I don't have anything particularly against the TV but I do try to limit the time that DC watch it for each day as I prefer them to be doing other things and really try to use it just for when I need to get things done (only way I can get some peace!) or for a bit of a wind down at the end of the day.
However we have been to a couple of playdates recently where the host obviously has the TV on all day and they don't turn it off when my DC are there. I find this a real shame as then the time that DC should be playing and interacting with their friends they tend to just spend glued to the TV instead. It feels a bit pointless going to "play" with someone when they just watch TV instead.
Is it unreasonable that people do this and would it be unreasonable or rude of me to ask politely that they turn it off? Or should I just accept that its their house/their choice?
