I am wondering if couples run out of topics to discuss about. Our discussion is always about cars, how people 'poke' him on expressway, where he & his friends drove to, what his friends did to their cars....

I know nuts about cars. Maybe he just want to share his thoughts with me but is always the same things to talk about: "CARS". In the past, when he drove fast, I will grumble. But now, I just keep my mouth shut because I understand no matter how much I grumble, it will still be useless. And I believe he needs concentration to drive the car, so it will better if he can drive peacefully.
