She knows basically nothing and has very little desire to learn. I'm allowed to drag her to 2-3 shows a year (so I pick wisely) and under no circumstances will she ever go to another swap meet again.
However she does like my truck which is a vast improvement over what she thought of my Mustang. She knows I'm really into them and that's all that matters to her.
Plus it gives me leverage for when she does something I have zero desire to do.
