Back when I sold and installed this stuff, I would try and insist that the wife stay while I am demonstrating the new toys and give her lots of eye contact.My husband is the technically challenged one in our house, and he is NOT adjusting well to the change AT ALL
My partner once asked, "How come you insist on teaching the wife?" I answered, "Because the husband is not listening and just wants the remote. SHE is listening and when hubby screws it up she will say, 'Eddie TOLD you how to work it'! ...so we're off the hook".
