My wife and I decided to have separate bank accounts that a small amount of money goes to each month. That way I can buy ammo and she can buy shoes and neither of us can say a word about it. We still have a joint account that 99% of our purchases go through of course.
not really grief, more the fact that she noticed there were more saws in the shed. She can do the same thing in the shop with tools, we will go out to do a project and she will pick out the "new" stuff. Not necessarily new but more of.
