I have to agree with the relationship to TV and LD
My H watches TV all the time, every single evening/night and has it on 24/7. It drives me wacko. I have talked to him about this and he simply refuses to turn it off. I have on occasion gone into the other room and turned music on and purposely turned it up. Maybe that was being nasty, but I sometimes get really wacked out cause of the TV on all the time. I have actually gotten him to eat dinner, and sometimes breakfast on the weekends, at the dining room table, but he always chooses the chair on the other side so he can still see the TV
