My wife does not mind my mods, but its very clear that she doesn't understand it. A few weeks back when she saw my steering wheel sitting in the passenger seat because I had just installed a quick disconnect just like your wife she shook her head and walked back into the house
She knows it makes me happy and as such she's good
Brenda just tells me to go ahead and buy the mods that I want, because she knows that they will show up at the house anyway.
