We don’t!
I have young adults now but I don’t think we have watched tv together for ten years apart from the very occasional thing that I might record for them that they might enjoy. They lose interest though and would never watch a whole series. I know times have changed and everyone has their own phone/tablet/laptop but it’s a shame. I remember watching tv with my family as a child and it was a really enjoyable activity.
Is it something you do in your house?
