Wife and I have a basic rule - Don't Know, Don't Wanta Know. I don't ask her what she has spent on her garden and crafts and she doesn't ask me what I spend on my hobbies. And as long as the basic bills (food, house payment, insurance etc) are paid on time, then we can pursue our hobby buying. The funny thing is that 30 years ago, when we were young, not making much money, trying to raise two young boys and haveing a really hard time making ends meet, I probably spent more per capita on modeling than I do now. Now I can walk into a hobby shop, look around and walk out without spending any money.
