Yep, same here. My wife rides but does not want to talk about/hear about/look at bikes when not riding. Heck last year I just about had to drag her to our LBS to buy her a new road bike and get her off that 10 year old hybrid. She is one of those people that uses something until it literally falls apart. She is a finance person and I am an engineer. It makes for some interesting conversations.

Finance person - "How much does it cost and what's the matter with your old bike"
Engineer - "This one has a wammer-jammer fork for greater responsiveness"
Finance person - "How much does it cost and what's the matter with your old bike"
Engineer - "It's a full 1.5 lbs lighter than the xx model"
