Because CHUDs have nothing else on their lives. Their adult kids hate them, and basically only come around for holidays. They aren't allowed at the Golf Course, due to an incident involving a golf Cart, a Caddy and seval thousand dollars in landscaping damage.
They have nothing to do except sit around and watch TV, flipping between one of twenty different copaghandha shows or Fox News.
The only place they can still be a nuisance, and not get kicked out for being so, is at public meetings.
