Well maybe not the marriage saver, and Mr.N pointed out that's a little bit extreme but it definitely help make ours work. I love T.V. the 8-10pm slot is a huge part of my day, I look forward to my shows every night. Mr.N loves hockey, the Maple Leafs more specifically and if you aren't aware for at least 7 months of the year they play on average of three games a week. Each game last 3 hours of prime time T.V. watching, and according to all men it must be watched live for full enjoyment.
The PVR saves us a fight, so we can save it for who's turn it is for the dishwasher or who cleaned the bunnies cage last. Anytime you eliminate a chance to fight you help make your marriage that much stronger.
Plus I can save my shows for a cloudy gross Saturday afternoon.
