Stella, that list is awesome. I'll have to think on that.

The 'bad habits' thing might give me a little leverage, just because she does enjoy a good wine, but is extremely frugal, so knows where to find what she wants for cheap. That and whatever bad habits she has, she enjoys sharing with me, and... I also enjoy partaking in.

That said, though...
yeah, biking things (especially my biking things...) last forever... wine, beer and amusements generally don't.

She does, however, like it when I prove my need for things. I showed her the saddle I wanted, and then the measurement of my sitbones, and my saddle... told her what that means, and why it hurts (since she's never around when I go riding, or post-ride)
She said "Black leather with rivets?! It'll get stolen right off your bike!" Then I told her about the fact that it's hard leather and she said "How can that be comfortable?!" ...and I explained. Then she said "If it's so wide, how will you be able to get back behind it for downhills without lowering the seat? And if you lower the seat, you'd have to stop and put it back up or you'd strain your knees."
... and I gaped.

She's really been listening to my endless bike babble, not just waving it off! EEE!

...so maybe for my b-day or something.
