I can see your point, if he is the only one that likes football. He shouldn't neglect the guests and family to watch football.
One thing I found since moving to Texas, Dallas Cowboys football is a religion. In our situation, I think it would actually be rude NOT to have the game on.cheesy
No joke, seems to be that way here! Lol... We have it on but never neglecting family. We still mingle with family while it's on.
