There are a very few things she doesn't seem to have a problem spending money on. Laundry machines. She'll buy the fanciest whiz bang washer and dryers that text you when your laundry's done. I'm not allowed to do laundry so I have no say.
It was her that picked out the RV...... $87,000!!!! HOLY CRAP!!! But normal chic stuff like clothes and shoes and handbags she's just not into. She likes interior decorating but she only gets a thrill if it looks good and it was cheap. It's the thrill of the hunt with a cost component.
I don't have to ask permission to buy a gun, but I do have to self-report. She asked me once how much ammo we had. The she asked if that was "prepper" level. I explained that while we did not have a "prepper" level of loaded ammo we had beyond that in components and tooling. For some reason she's fine with me buying all the ammo/components I want. She had me order a couple of cases of 20ga buckshot for her shotgun back when it was plentiful.
